Heroslayer:
Heroslayers are like goblins being fast and fragile, but do 2x damage to heroes. They also have cloak on them for the first few seconds they are deployed (like a queens royal cloak) or come out of a clan castle, which allows them to be temporarily shielded while running towards their favorite targets.

Alternately instead of being cloaked, they can jump over walls like hogriders only if they are heading directly for an enemy hero. If no heroes are within range they will target other army units over defenses/buildings/walls, so in a raid they target heros, then clan castle units, and dealing 1.5x damage other army units.
Rage Demon:
Rage (or Chaos) Demons are just like healers, but instead of healing their troops they affect them with Rage like the spell. They are an exact mirror to the healer, instead of being angelic - they are demonic, looking more like a minion.
