When to Use Lightning Spells
Room Clears
Lightning’s chain mechanic shines when fighting groups of enemies. In rooms with 3 or more enemies clustered together, a single lightning cast can damage 2-3 targets simultaneously, making it dramatically more efficient than fire or melee for the same mana cost.
Crowd Control
When enemies are grouped (goblin packs, crawler swarms), lightning provides the fastest room clear with minimal risk.
Secondary Spell
Pair lightning with fire on your second hand. Use fire as your primary spell for bosses and lightning as your room-clear spell for general dungeon crawling.
Chain Lightning Mechanics
The chain mechanic triggers under specific conditions:
- There must be an enemy within 3 meters of the primary target
- The chain targets the nearest enemy to the primary target
- Chain lightning does not chain a third time — maximum two targets per cast
- Chain damage is fixed at approximately 50% of the primary strike’s damage
Lightning vs Fire
See the Fire Spells page for a detailed comparison. In summary:
- Use fire for boss fights (higher single-target burst)
- Use lightning for dungeon room clears (chain efficiency)
- Carry both spells and switch based on encounter type
Mana Management
Lightning costs 10 mana per cast (versus 15 for fire). Your total mana pool of approximately 100 mana gives you 10 lightning casts per full bar. Do not waste lightning on single targets when melee would suffice — reserve mana for the situations where the chain mechanic provides value.
