I decided to make a guide for people who picked lions and I see some people pm me in game asking questions mostly everyday. Well in this guide I'll try to give as much information to help you guys out. Note that this guide is for mostly lions who chose to be a gun type character so lions who picked to melee, I recommend you check the guides for foxes.
Builds
Your build is your Power/Magic/Sense/Charm. Power is your Attack Power (AP), Accuracy(AC) and your Dexterity(DX). Magic will be your Magic Attack(MA), Magic Defense(MD) and your MP. Sense is your Luck(LK), Detect Ability (DA) and Weight (WT). Charm is your Defense(DP), Hit Evasion(HV), and HP. If someone asks you if your build is either 1144 or 4141, it means 1Power/1Magic/4Sense/4Charm for 1144 and so on. Each builds have their pros and cons.
Bonus Points
In the game, every time you level up you gain 4 bonus points. You can choose where those points will go. Since you are a sense type, it's a good idea to put it in the sense section but the stat that determines the gun dmg for lions is accuracy so add them there.
Pure AC: This is a recommended build for gunner lions. The more AC you have, the more dmg you deal. This is the most common stat where lions put their points in.
Pure LK: You won't be dealing as much dmg as pure AC but your dodging and block rates will be HIGH. Monsters will keep missing and you will keep blocking. Also you'll have a high chance of getting good results in compounding. You'll be leveling at a slow rate though if you are a gunner/Pure Luck. I'd rather recommend going pure luck if you're a melee lion. Also if pure LK isn't that bad when Trickster releases Fortune Hit which really PWNS bosses as the more HP the enemy has, the more dmg you deal. You don't have to be pure LK to get this.
LK/AC: Decent dmg. You will be dodging and blocking more than Pure AC but not as much as pure luck. You'll have high compounding chances but not as much as Pure LK. So this build is kinda in the middle.
3142 Build: This is a common build for lions. You'll have a good amount of damage. You're defense and hp will be low. If you chose this build, wearing a good high luck hat will make up for the low hp that you have. Defense gears might also help you but I prefer luck.
2143 Build: Mostly another balanced build. More HP than 3142 but less damage.
4141 Build: I HIGHLY recommend to not choose this build. You'll be dealing SUPER HIGH DAMAGES, but you will be sacrificing your HP and you will die easily in higher levels. Only choose this if you have ownage luck/HV equips or if you're deciding to change to another build using Graph Reset from Myshop later on.
1144 Build: I see this build is often picked. You will have decent health and decent defense. In doing that, you will be sacrificing your power. It will take you a while to level but getting good AC guns and equips will help.
1342 Build: Not recommended. You will have more MP but your HP will be low and the dmg you deal will also be low.
1441 Build: Not recommended. It's worse than 4141. Barely any dmg or hp. Your MP is not that important since it will catch up on higher levels.
NOTE: If you choose a defensive build, I advise you to wear HV Hats. If you chose an offensive build, I advise you to wear LK Hats.
Spots for leveling
NOTE: You will not be able to use a gun until level 15 so you will have to melee/dig yourself till then. When leveling, it's a good idea to try to find a 2.5x Special/Royal party for faster exp. If you cannot find one, soloing actually helps rather than sitting and waiting for a party. Just do quests, they help also.
This leveling guide will be starting from when you are level one. When you begin the game you either get sent to Coral Beach Paradise or Desert Beach Paradise. I recommend that if you get sent to Coral go to the npc near the skill shop. Her name is Rosemary. Talk to her and by paying 10 Galders you will be sent to Desert Beach. Just get the 10 Galders from the nearby monsters in Coral. If you get sent to Desert then I suggest you stay there.
Level 1 
Fanta Slimes are good experience. Just keep wacking them till you reach level 3-4. Fanta Slimes can be found in Beach Field 4- Parasol River
Level 4
Once you reach level 4 it's time to kill these guys. Just keep wacking them over and over.
These guys are good to train on till around lv 6-7. Found in the same map as Fanta Slimes.
Level 7

These guys are very good exp. The mole drops earthworms and you need those for a quest in Gate of Desert Beach. At this level try to get into 2.5x Parties. Stay with these guys till level 10. Found in Beach Field 3 - North
Level 10 
You are almost there till you can use a gun! Just a few more levels. When training on Fanta Fish, get ready to use HP Potions because they can deal some damage. Level here until level 13. Found in Beach Field 5 - Sand Palace
Level 13-15

Woot, once you're done with these guys you are going to be able to use your gun and own them. Try leveling here until level 18 with a good party. Found in Beach Field 2 - Center
NOTE:You can use your gun now. Go to any npc Item Girl and buy it there. Also don't forget to buy ammos.
Level 18 
You have two choices when you get to level 18. Either go to Seabed Field 4 - Undersea Grave to train on >>Popeye<< Anemones not Bad ones. They are good exp, especially with a party.
Level 20 
These guys are gun protection but you'll still be getting good exp and decent dmg. Once you reach level 25 you have options. You can either keep training or if you're too lazy do the nora quest all at once and get to 35. Same map as Popeye Anemone.
Level 25
Just get a party either royal or special. Recommended to stay here till 30.
Level 30 
This will be fast experience, since these guys are gun weakening. You'll be able to do a lot of dmg to them. You just need a good 2.5x party and you'll be zooming your way to lv 34. Another option is that you can also train on Bad Anemones. There are quests for them beginning at level 30.
Level 35 
Mostly try to kill the tigers because they are gun weakening and don't deal that much damage. You'll be staying here for a while which is staying here until level 48. You can also try to kill Gomas once you're around your 4x levels and level off of them till lv 50.
Royal/Special parties are very important here. Easy money also. Found in Path to Oops Wharf.
Level 50 
&

or

You have some decent leveling spots once you reach level 50. You can either go to Path to Phantom School and train on Gallis and Hallis. There is a Galli quest you can do and you can easily make money from them. Your second choice is going to Phantom School and kill Mary Dolls. Either way, stay with them till lv 65.
Level 65 
or

The Aposis are gun weakening and parties are pretty easy to get on where they are. There is a quest for Electric Snails so either one of these guys are awesome to train on. Stay with em till level 80.
Level 80 
Even though these guys don't look like they give much exp, oh yeah do. If you don't like them you can always fight the Swamp Sharks that's in the same map as them. There are tons of quests that can be done at 80+. They are in the quest section of the guide. Swamp Sharks and Frogs can be found in swamp 2 by the way. Level off of them until level 95-101.
Level 101 
These guys have awesome exp. Especially with a good royal/special party. You can also make a lot of money from the drops here. You don't have to come here at 101, Lving here around your 90s is also fine or do your Swamp Shark Quest. Beware of the MudBigfoots, they hurt and they are gun protection. Arachnes are good till you are done with the Arachne quest, you'll be around 124 once you're done with them. Found in Swamp 6
Level 124+ 
or

I deleted the Kilimanjaro because these past couple weeks, I've noticed not many lions train at Tech 1 as they used to. I'm not saying you should'nt, they're still pretty decent EXP. After you're done with Santa Bears or passed level 150, you're good enough to start at Tech 4 which is a very popular map these days. Parties are easy to get here and there are tons of mobs. Aabon and Dekumanu give awesome galder amount and NPCable equipment and since Tabasco is out, the repot is just one map away ^-^
Monster(Base EXP)/Item Quests(Base EXP)

NOTE: I only put based EXP quests here if you want to rush through leveling. TM quests are also important but I will add those later on.
Suggested Accessories/Pets/Hats when training
Level 10: Use Contact Lens and Lucky Amulet. For pet use Ice Cone/Baby Rabbit/Baby Buffalo. Just buy one from an NPC if you need a hat.
Level 30-50: Use Necklace Watch/Acceptance Trunks or Witch's Trick Ring and compound it. Keep using Ice Cone till level 50 then change to Chuck E. This is wear you start wearing LK/HV or DP hats. Use a Craft/Custom/Master Felt Hood and compound it.
Level 60-70: Use your job change ring if you got it and use Necklace Watch or Acceptance Trunks with it till your 70 then change to Rythm Earrings which are VERY helpful. Keep using Chuck E and now you ca change your hat to Berets. Suggested to start dealing with LK hats.
Lv 80-100: Job Change Ring/Rythm Earring or if you picked a low HP build Chu Amulet/Rythm Earrings would work just fine. Use Red Fairy till 100 then change to Red Fairy Angel. Keep going with those LK hats as you will miss more on the enemies around this level.
Lv 100+: Stay with your Red Fairy Angel and the same accessories as before. Just keep get better LK hats as you level further because they help you crit and help you block from enemies attacks.
-Quick Note on Equipment- Myshop is released now, and the equips I have stated above are for people who do not decide to buy myshop or cannot afford them.
Skill Builds
Trickster Online has now released all 2nd job skills.
First Job (Engineer)
Stone Strike Level 10 (Requirement for Armour Destructor) - TM Level 1
Gun Carrier -TM Level 15
Invincible Reload - TM Level 25
Gun Booster - TM Level 30
Quick Reload - TM Level 40
Armor Destructor Level 1 - TM Level 40
Job Change (Inventor)
Stone Strike Level 10
Power Shot Mastered - TM Level 55
Lucky 7 Mastered - TM Level 50
Shooting Spree (Roulette Shot) Mastered - TM Level 70

Sticky Foot (Optional) Level 10 - TM Level 20
Sixth Sense (Optional) Level 10 - TM Level 1
3rd Job (Pure Gunner- Scientist?)
Violent Shot Mastered -TM Level 135
Optics (Correct name?) Mastered -TM Level 130
3rd Job (Hybrid-Cyber Hunter?)
Aura of Luck Mastered/Level 10 - TM Level 70 [Required skill to get this is Lucky 7 level 10]
Sticky Icky Mastered/Level 10 - TM Level 105 [Required skills to get these are Sticky foot level 10 and Armour Destructor level 10
Landmine Mastered/Level 10 - TM Level 90
Pouch of Pain Mastered/Level 10 - TM Level 115 [Required skill to get this is Heavy Carrier]
*Level 10 and Mastered are not the same. After you get a skill to level 10, it can be potentially get stronger by mastering it which usually cost a lot of TM.
*As the rumor goes, 3rd job is coming out before summer ends? So I guess I'd put on the recommended 3rd job skills you should get and what order you should get them.
NOTE: If you're confused about getting Lucky 7 or Shooting Spree first, either one is fine. I recommend Lucky 7 though since huge mobs don't come till later on. If you want to get Spree a bit faster, just get Lucky 7 to lv 10 and master Spree first or get them both lv 10 and do TM quests and master them both. It's really your choice.
*I put in the additional skills that most lions don't get because even though you'll be using a lot of tm points, you'll level your tm a lot anyways. Don't really think like "Oh if I get this I'll be wasting points for 3rd job" The card quests are out now and probably very easy to obtain more TM points.
Tips on making money as a lion
If you are short on money, there are many ways to get a decent amount
A) You can just level and pick up everything that the monster drops. Most of the times, the npc buys them for a high price so don't just leave them on the ground. By doing this, it might slower your leveling rate since you're taking your time by picking up everything you see.
B)When you are not playing and just leaving your character there, don't do that. At least try to vend some items so when you're not doing anything, you might make money.
C) You can always gamble by compounding but try doing it with high luck. Compound an item and get a godly result. Then you can sell them for a much higher price. This is only for when you have extra money. Be sure to remember that you also use money when compounding the item. You can also refine items to high levels. Highest I've seen is level 11. Also remember Compounding is kinda random so be careful before spending lots of money on it.
D) Go on a bossing hunt and sell the master equips that you get. Or be a merchant lol and buy stuff for cheap and go sell em for a higher price but this is kinda difficult to do so this is not recommended.
E) Wait for items to be in demand and THEN sell them. Sometimes events come in or new quests come in or anything new can affect an item's price. It will either go up and go down. You just have to think that if its price will go down soon enough, then try to sell it as soon as possible. If you think the item is going in demand in the future then let it sit in your bank and when the time comes, people will be wanting it so much that they will desperate to buy it and offer you something HUGE!
Job Change Items
Before you can proceed to becoming a 2nd Job Inventor you need the following items.

2 Natural Gases
Watches and Glasses are dug in Rose Garden. Petros and Gases are dug in Ghost Blue.
PvP Advices
PvP these days is very difficult considering all 2nd job skills are out. Doing the following against each class should help a bit.
Bunny & Buffalos: If you are against power types it can get pretty difficult since most of them get vibe. But if you get the right equipment and the right amount of HV, you might just be able to win. If you lose, well don't worry, lions were made to lose against powers..zzz...
Sheeps & Dragons: This class is quite easy to go against by using the right equipment and the right HP amount. If you get the right amount of luck, most of their magic skills will miss you while you go barrage them with your combos which leads them to just decide to keep curing. Also, watch out for some mages because some of them have high luck AND high damage since myshop is out.
Racoons and Cats: Ok, I know Ntreev made it for sense types to "own" charm types and I agree with them but I have an arguement. Since Mutation is out now, most Racoons get insane HV which causes us lions to suffer and do no damage at all, unless you get lucky and the revert back to their normal form. Cats on the other hand might be possible, just wear a good compounded HV hat and a good amount of total HV and most of their skills will miss. If Cats use Evolution, their HV just goes down which makes you do more damage but I don't think most cats would do this against lions anyways lol.
Lions & Foxes: Ohh..now you're up against your own type lol. Makes if pretty difficult since they have 4 in sense as well making them get a good amount of luck. First up foxes, if you're against them use HV also because the accuracy of their skills aren't that good (no offense) but luck foxes are a different story. HV equips might not work for them since they'll just kill it with Sticky Icky and by wearing HV, it will just cause you to miss since their luck is insanely high, the only advice I can give is just boost up on luck equipment. Now if you're against a lion, then either boost up on LK or HV.
!!Important Note!! In PvP these past couple days, I've noticed lions wear all their luck equips then switching to gun thinking that have more luck just because the stats shows you have more than if you just use lucky 7 with your gun alone. But the problem is, doing this switch technique does NOT work. If you don't believe me, just try your damage using Pistol Hit (Fortune Hit) with your gun and the regular accessories and buffing up lucky 7, then after seeing your damage do the luck equips to gun switch then buff up lucky 7. If you did it right, your damage is still THE SAME which shows your luck has not changed one bit.
Boss Hunting Advices
Lions are good at killing bosses because of their good amount of luck and speedy attacks. But these days, I still see some complain of how they either miss to much or die too much. Look, if you're deciding to be a boss maniac later on, don't bother picking the risky low HP builds because this will be no help to bosses such as Queen Odinea and Spicy Dragon.
Anyways that's my guide. I will keep adding more informations as soon as I work on my lion. If you think I have any mistakes, please kindly tell me. PM me if you have any other questions.
-Note- Now that myshop is out, most lions can easily level.
