Trap Warden

 
Prerequisite(s): Any Least, Lesser, Greater, Siberys Mark of Finding
 
Benefit: Once per day you can reroll any one search or disable device check. The decision to reroll must be made before learning the outcome of the first roll and you must take the second roll regardless. If you have the lesser mark of finding, you gain a +1 bonus on reflex save to avoid traps and a +1 AC bonus against trap damage, if you have the greater mark of finding or the siberys mark of finding, your bonus increases to +2 for both. These bonuses stack with the rogues trap sense ability.
