{{ rpd:images:mana_icon.png|Mana Icon }}

**Mana** (also known as Skill Points) is a resource system in Remixed Dungeon that powers spells and magical abilities for certain classes and character builds.

==== Overview ====
Mana represents the magical energy required to cast spells and use magical abilities. It's a limited but renewable resource that players must manage strategically. In the game code, mana is referred to as "skill points" and is tracked as the SP (Skill Points) system.

==== Mechanics ====
  * **Regeneration**: Mana regenerates through the ManaRegeneration buff which grants 1 skill point at regular intervals
  * **Regeneration Rate**: Regenerates 1 skill point every 20/(1.2^bonus) turns where bonus includes various factors
  * **Capacity**: Maximum mana is determined by skill point maximums, which increase with level
  * **Consumption**: Spells and special abilities consume a specific number of skill points
  * **Regeneration Delay**: Outside of safe areas (shops, altars), mana regenerates more slowly
  * **Bonus Regeneration**: Certain buffs and subclasses can provide mana regeneration bonuses (e.g., Shaman subclass)

==== Usage ====
  * **Spell Casting**: Most spells require a certain number of skill points to cast
  * **Special Abilities**: Class armors and other special abilities consume skill points
  * **Resource Management**: Players must balance skill point use with other resources
  * **Class Armors**: Warrior armor abilities, Mage staff powers, and other class-specific abilities require skill points

==== Classes and Affinities ====
  * **Rogue Class**: Uses mana for throwing spells like [[rpd:kunai_throw_spell|Kunai Throw]]
  * **Shaman Subclass**: Provides mana regeneration bonus through HeroSubClass.manaRegenerationBonus()
  * **Mage Class**: Has direct access to wand and spell mechanics
  * **Other Classes**: May gain access to mana-based abilities through special means

==== Technical Details ====
  * **Java Class**: [[https://github.com/NYRDS/remixed-dungeon/blob/master/RemixedDungeon/src/main/java/com/watabou/pixeldungeon/actors/hero/Hero.java|Hero.java]] - Contains SP (skill points) system implementation
  * **Regeneration Class**: [[https://github.com/NYRDS/remixed-dungeon/blob/master/RemixedDungeon/src/main/java/com/watabou/pixeldungeon/actors/buffs/ManaRegeneration.java|ManaRegeneration.java]] - Handles automatic mana regeneration
  * **Methods**:
    * **getSkillPoints()**: Returns current mana value
    * **getSkillPointsMax()**: Returns maximum mana capacity
    * **spendSkillPoints()**: Reduces skill points by specified amount
    * **accumulateSkillPoints()**: Adds skill points to current value
  * **Regeneration Formula**: 1 skill point every 20/(1.2^bonus) turns with various bonuses factored in
