so ive been playing for a while, but have been saving most of my perk points, i spent some in what i thought would help me be an assassin picklocking type character, but i read somewhere that i should have illusion aswell? whats the best way to go about this build... Right now most of my perk points are in Sneak, archery, picklocking , 1 handed and light armor not to many in each i have a bunch still saved up im only level 15. So should i put perk points into illusion???

If u do only go to silent casting. But no I wouldn't.

TBH, archery isn't that useful for a thief. You're going to want to go with one-handed (for daggers), sneak, lockpicking, illusion, light armor, and pickpocketing.

i only have 1 or 2 points in archery, why is illusion helpful??

Illusion is helpful because it gives things like detect life, invisibility, etc.

ah okay thanks, ill start putting some perks in illusion

my character is sneak/thieve/assassin based and i have all mine in archery, sneak, and one hand, level 16 and have 3 or 4 saved up, some r in light armor too
