Your killing blow sets off a chain reaction of inspired attacks, potentially laying low all your foes.

Encounter   ✦     Martial, Weapon
Standard Action      Melee weapon

Target: One creature

Attack: Strength vs. AC

Hit: 1[W] + Strength modifier + Charisma modifier damage. If this attack reduces the target to 0 hit points, an ally within 5 squares of you can make a basic attack against a different target as an immediate reaction, adding your Charisma modifier to the damage roll. If that ally's attack reduces its target to 0 hit points, a different ally within 5 squares of you gains the same benefit. Repeat until an attack fails to reduce a target to 0 hit points or until you run out of allies within 5 squares.
