Lets start a list (Hopefully a short one).
1) Past Life: Rogue. This currently does give +2 to saves vs. traps, but the +1 to sneak damage is not being applied, or possibly is not stacking with the rogue sneak damage enhancement (or even worse, the natural rogue sneak attack feat).
How I tested: For traps, I stood in a trap on a lvl 2 rogue with a +6 reflex save. Without any other feats or enhancements, I was getting rolls of 1d20+8 to save vs traps, so this part seems to work fine. As for the sneak attack damage, the same rogue (1d6 natural SA) with one tier of SA damage (+3), and a past life as a rogue (+1 damage) should have generated sneak damage of 1d6+4, or 5-10. I was getting 4-9 consistently through over 200 observed sneak attacks. Bug reports will be filed in the morning, I had to log off for bed.
Anyone else find a flaw in their past lives?
