Smite is nice... it is quite effective against larger forces... the knock away ability was a lifesavor when fighting duergar swarm with Sarevok alone...
Whirlwinds are helpful, but not as good as the one smite you get... Hardiness is a staple, barbarian too... lol Use Any Item is ridiculously overpowered, and so are most of the thief traps. Still, other theif ones kinda stink, so just take those anyway...
LOL! Warcry was only used by my 'fearmonger'... a fun fighter. He got rockhelm, ravager and warcries... EVERYBODY was scared of him... Oh, and used terror rod too. lol really a weak character, but would make mincemeat of an army of gobos and orcs.
Resist Magic isn't all that great. ASSASSINATE is TRULY evil when you have a thief or assassin with lots of attacks per round (like 5 without haste...
can be done...)... Then, you get LOTS of killing power...I did max damage (around 500 or something. No, less than that...) with my Kensai/Thief using staff of ram, a critical hit and an assassination. VERY funny.
