I used my +20 heart to LR to all Arti (to get an Arti past life) then TR'd to Drow Elf. I like Drow Elf for its ability to get +3 more INT than human and I like drow elf racial tree for this build a tiny bit better. Human is still a good choice, tho. Basically, the only real difference is humans get an extra feat, -3 INT, and the ability to have haste and damage boost active at the same time compared to drow. I also went dex as secondary stat instead of str, after playing around a bit the last week or so, I think it really works well now with the new enhancements and you only have to put points into 3 stats instead of 4. I started with 8 STR, 16 DEX, 14 CON, 20 INT, 8 WIS, 10 CHA. (36pt build). All level-ups into INT. a +5 dex tome qualifies me for improved sneak if I decide to take it. Overall U19 brings some nice improvements to this build. (except for the TR part
).
