You being new to the game, i would suggest 1144 build.(power,magic,sense,charm) This is a good starter and most common lion build as lions are the most fragile class. If your looking for the max damage build, you'll want to choose 4141(this really brings out the glass cannon in the lion though, and leveling up with this build is frustrating as you'll die pretty much all the time(don't choose this if you plan to PVP).
If you want to have some punch behind ur shots, you'll want to put stat points into AC, but if u want to make you shots more accurate you might think of putting them in LK(this is i only recommended if u plan to PVP). Just keep in mind these are the ONLY 2 stats you want to put points in, everything else you can make up with equips.
I myself am a 2143 build, because i wanted some more damage at higher lvls at a risk of dying more, and if u go with this or 3142 you wont see much of a difference in damage until your higher lvls.
Hope this helped!
