Location:
Volcano Dungeon, various floors.
Strategy:
Hot Heads are flying enemies that shoot fireballs. They are similar to Bats but more dangerous. Their fireballs can inflict the 'Burnt' debuff, which drains health over time. Prioritize them to avoid taking continuous damage. Use a fast weapon and try to close the distance quickly. If you have a Slingshot, Explosive Ammo can be effective. Bring plenty of healing items and consider the 'Immunity' stat from rings/boots to resist debuffs.
Rewards:
Cinder Shards, Magma Geode.
