WIL 3
INT 5
throwing
melee
dodge
evasion
stealth
hacking
lockpicking
pickpocketing
essential start gear:
sledgehammer
motion goggles (to compensate for shitty detection)
any armour with a stealth bonus
any boots with a stealth bonus
later gear:
lifting belt
shock hammer
shock knife (to squeeze every last bit of damage out of leftover AP)
shield emitter
rathound regalia (seriously this thing is so OP)
tabi boots (when combined with regalia you can run from any situation that gets too bad. also dat stealth)
start feats:
conditioning
opportunist (because chance to stun with sledgehammer)
essential later feats:
reckless
paranoid (again for detection boost and to cancel out +3% chance to be crit)
dirty kick
cheap shots
(these last two synergise fantastically with opportunist)
other later feats:
interloper
bone breaker
cut throat
eviscerate
(these last two are great together but take such a long time to get together)
yeah so this build will tear through pretty much anything. pickpocketing hacking and lockpicking make you so goddamn rich. i feel like mercantile needs to do more and money just needs to be a lot harder to come by, my late game battery habit doesn't even dent my stacks and stacks of money.

the build actually feels quite balanced, up until the point where you get the shock weapons. also the bonuses on the rathound regalia mean it should have a much lower defensive stat. i also think constitution should play a much bigger part in defence; with dodge and evasion so high on the off chance that anyone actually hits me 5 con and conditioning soak a good amount of it up. honestly the only thing more OP than this build is endgame psi imo.
