====== mr:ghost_npc ======

Machine-readable reference page for the Sad Ghost (quest-giver NPC) in Remixed Dungeon.
Note: this page previously existed as "mr:ghost_mob" and incorrectly described a nonexistent combat mob; all facts below are grounded in the actual implementation.

{{ rpd:images:ghost_sprite.png|Ghost NPC }}

==== Java Implementation ====

**Class File**:
  * File: [[https://github.com/NYRDS/remixed-dungeon/blob/master/RemixedDungeon/src/main/java/com/watabou/pixeldungeon/actors/mobs/npcs/Ghost.java|Ghost.java]]
  * Path: com/watabou/pixeldungeon/actors/mobs/npcs/Ghost.java
  * Entity Kind: Ghost
  * Type: **NPC** (extends NPC, not a combat mob)
  * Sprite config: spritesDesc/Ghost.json

**Note**: There is no combat mob named Ghost in the codebase. The generated entity list (entities/mobs.txt) contains "Ghost", but the class is an NPC quest-giver spawned on SewerLevel via ''Ghost.Quest.spawn()''.

==== NPC Properties ====

**Basic Stats** (from the Ghost.java constructor and method overrides):
  * HP: not damageable — ''damage()'' is overridden to a no-op
  * defenseSkill: 1000 (''defenseSkill()'' returns a constant)
  * Speed: 0.5 (''speed()'' returns 0.5f)
  * Flying: true
  * EXP: none
  * Immunities: Paralysis, Stun, Roots (addImmunity in constructor; ''add(Buff)'' always returns false)

**Lua Definition**:
  * No Lua script - implemented in Java

==== Behavior ====
  * Wandering AI state by default
  * Once the quest is given, 10% chance per turn to follow the hero's control target position
  * Teleports randomly if interacted with again before the quest item is obtained

==== Quest Mechanics ====
  * Spawned on SewerLevel when depth > 1 with probability ''Random.Int(5 - depth) == 0''
  * Two quest variants chosen at random (''Quest.alternative''):
    * **Rose Quest**: find the Dried Rose; it drops after killing mobs (''Random.Int(left2kill) == 0'', left2kill starts at 8)
    * **Revenge Quest**: slay the Fetid Rat spawned by ''Ghost.Quest.process()''
  * Reward: weapon and armor via ''Treasury.bestOf(category, 4)'', identified
  * **Necromancer Interaction**: Necromancer heroes can persuade/dominate the ghost via WndSadGhostNecro (''persuade'' flag bypasses the item requirement)
  * Journal entry: Journal.Feature.GHOST

==== Inner Class: Ghost.FetidRat ====
  * HP: 15, defenseSkill 5, attackSkill 12, dmg 2-6, dr 2, expForKill 0
  * Emits ParalyticGas on ''defenseProc''
  * Carries RatSkull; immune to Paralysis

==== Content Verification ====
  * **Source**: Java class `Ghost.java` in `com.watabou.pixeldungeon.actors.mobs.npcs` (extends NPC, not Mob)
  * **Stats verified from code**: defenseSkill 1000 (invulnerable), speed 0.5, flying=true, immune to Paralysis/Stun/Roots, no damage taken (damage() is no-op)
  * **Quest mechanics verified**: Spawns on SewerLevel depth>1 with probability Random.Int(5-depth)==0; two variants (Rose/Revenge); reward from Treasury.bestOf(category,4) identified
  * **Necromancer interaction**: WndSadGhostNecro window with persuade flag bypasses item requirement
  * **Inner class FetidRat**: HP 15, defenseSkill 5, attackSkill 12, damage 2-6, DR 2, exp 0, emits ParalyticGas on defenseProc, carries RatSkull, immune to Paralysis
  * **String resources**: Ghost_Name, Ghost_Desc, Ghost_Rose1/2, Ghost_Rat1/2, Ghost_Defense in values/strings_all.xml and values-ru/strings_all.xml
