Maxed out UMD, disable device, open locks & concentration at most levels. Is the UMD useful endgame at 23? I went with the trapmonkey skills for usefulness to parties along the way, are they going to be able to cut it where they are?

Other gear that I couldn't put in the planner: MinII Khopesh, STR 9 Khopesh (STR 33/34 with tome), GS Belt of Stalemate for 300 SP WIS 6, Dragontouched Armor...

Deviated very little from Tihocan's build. End goal is to not always wait for a rogue along the way and build up my DPS from the pure ranger he is now...

Any advice / criticism is greatly appreciated. Thanks!
