Available to any character with one or more levels in Fighter, or with three or more levels in Thief or a Thief sub-class. Use this deed only when you and an ally have both successfully hit the same foe in melee in a given combat round. Your ally must also use Coordinated Strike this round.
Sacrifice a Risk Die by rolling it. Compare your Risk Die Result with that of your ally. Pick the higher result. This is the Preferred Risk Die Result. Choose the better damage result from your damage die/dice result and that of your ally. This is the Preferred Damage Result. Sum the two and apply it as damage to your mutual foe. If using Scarlet Heroes damage, add 1 additional HD of damage for every two full points that this sum is above "7". Example: 16 would resolve to 8 HD of damage dealt.
If the two of you would have dealt more damage without Coordinated Strike, apply uncoordinated damage instead. Both you and your ally who also activated this heroic deed gain a one percentile improvement to an Ability Score of your respective choice.
