====== Immortal NPC ======

**ImmortalNPC** is an abstract class in Remixed Dungeon that extends the base [[en:rpd:npc|NPC]] class. NPCs that inherit from this class have special properties that make them essentially invulnerable to damage and unable to move.

  * **Low Speed**: Speed is set to 0.5f (slower than normal)
  * **Buff Immunity**: Cannot receive or be affected by buffs (add(Buff) returns false)
  * **Defensive**: Uses "wails" as its defense verb (from Ghost_Defense string resource)
