Still playing my first "real" rogue character (a TWF assassin-style build), and I took precision on the idea that it would be useful for ensuring I get sneak attack damage. My experience so far is that it does nothing to help against SA-resistant foes (undead and constructs, who are "immune" to SA and not just 100% fort), and whether I turn it on or not doesn't seem to matter for anything else. The +5% to hit sounds nice, but as it's % and not *+5 *to hit, the impact is pretty marginal.
Currently lvl 14. It is useful later? (bearing in mind that I already have Opportunist, and the Assassin's Trick core ability grants a chance to reduce fortification AND SA immunity by 25% for intelligent foes) Useful only on certain settings, like EE?
Thanks in advance!
PS: Assassin's trick has never worked on intelligent undead, despite me being a max-Int, pure rogue build. Be interested to know if anyone else has got it to work.
