Heroic Deed: Improved Ambuscade

Available to anyone with at least one level in Ranger, or four levels in Thief, or one level in Cutthroat. Expend a Risk Die from your Risk Dice Pool by rolling it. As long as the result isn't '1': Apply the Risk Die Result to your first attack in an ambush you join or orchestrate (that occurs within {your [choose one: Cutthroat/Ranger/Thief] level(s)} hours). The bonus applies to the to-hit roll. Should your initial ambush attack succeed, add the Risk Die result plus your Dexterity modifier to your combat damage and/or to the rolled damage of a trap you've set. Both you and your allies in the ambush gain the to-hit bonus, but only you gain the damage bonus. These bonuses apply only the surprise round of the ambush encounter. For each victim slain or immobilized by your ambush, there is a 1% cumulative chance that you gain one percentile point to your Dexterity ability score.
