Sounds almost too good to be true:
You have +1 to all skills and three times per rest you can skulk with the skill of your past life, gaining bonuses equal to your level to your hide and move silently skills, a +1 bonus to sneak attack damage for every two character levels after first, and a +1 bonus to hit with sneak attacks for every four levels.
So a level 20 rogue gets +20 to hide and move silently for one minute three times per rest?
Also, can someone point me to a good DEX-based two-weapons elf rogue build?
