Guardian Carol is a Hunter hero, with the following Leader trait:

Coup de Grâce

Every time Carol's main attack does not kill her main target, she has a X% chance to deal an immediate follow-up attack for Y% of full damage.
In addition, whenever she inflicts a status effect, you have a Z% chance to gain a charge point.

As a leader, all team members receive this bonus.

Notes:
• Follow-up attack only happens on active attacks (so not overwatch, retaliate, punish etc.). If a charge attack does not kill an enemy, the trait can still trigger
• The Follow-up attack happens immediately after the main attack, so e.g. traits like Firing Squad, Swift Strike (weapon trait), enemy's retaliate, will happen only after the follow-up attack
• Both the X% chance and the Z% chance get boosted by the Lucky trait
• All other traits that buff damage, give chances for attacks to inflict status effects, or gain extra charge points etc. will apply to the follow-up attack
• Stuns inflicted by a Push collision are not considered directly inflicted by the survivors
• If the enemy is pushed out of range on the first attack, the follow-up attack will not happen
