Trap Sense
Effect:
Even rogues whose backgrounds don't have anything to do with noticing, avoiding, or disarming traps have a unique knack for dealing with traps.
If a rogue's skill check involving a trap is a natural even failure, the rogue can reroll the skill check once. If a trap's attack roll against a rogue is a natural odd roll, the rogue can force the trap to reroll the attack once.
Adventurer Feat:
The trap attack reroll can also apply to a nearby ally of the rogue as the rogue shouts a warning or acts to prevent the trap from hitting.
Champion Feat:
You gain a +3 bonus to skill check rerolls you make against traps.
Epic Feat:
You only take half damage from trap attacks.
