Hitman
"Some warriors fight armies—the Hitman needs only one name. Silent, precise, and often unseen until it’s too late, the Hitman devotes themselves entirely to eliminating a single target. Whether driven by coin, orders, or personal vengeance, they may spend days or decades in pursuit—waiting for the perfect moment to strike. Their methods vary—blade, poison, bullet—but their focus never falters. A Hitman can change the course of history not through war, but through one well-placed death. They care little for politics or chaos—only the mark matters. Some vanish after one mission; others live from target to target, becoming myths."
The Hitman's playstyle depends on choosing a target within the battle, causing your attacks to be focused on said target but unable to deal any damage to any other creature on the battlefield. As a Hitman, you may mark a Hit in the battlefield, and that creature must die for you to be able to mark another. After killing a Hit, you have increased movement speed and can use a bonus action to hide.
Abilities:
Mark Hit – You mark a creature as your hit. The creature takes raised damage from you, has higher critical chances from you, has disadvantage against saving throws from you and you have advantage against them. Once your Hit dies, you must wait one to two turns to mark another.
Retributive Execution (Reaction) - If another creature kills your Hit, you may: Mark that creature as your next hit instantly if it is an enemy, or provide a stat buff to that creature if it is an ally.
Tactical Entry (Reaction) - If your initiative rolls low enough at the start of battle, you may use this reaction to instantly Mark a Hit before your turn.
Silent Strike – You shoot your pistol with a silencer, raising your chances to not be discovered from it if hidden.
No Witnesses – You teleport to a corpse on the battlefield to retrieve the corpse by teleporting with it elsewhere, allowing it to be looted by allies or to be taken into or out of necromancing reach.
Ultimate Ability – Contract of Many – All enemies on the battlefield become marked as your hits for 3 turns. After the 3 turns, you choose two enemies to remain as Hits until they die. All stats on hits are raised for the 3 turns.
