Haja

A hot spring owner found in Ancient Chaos. He gives you temporary access to the hot spring for 30. This particular spring will overheal you, increasing your life 32 beyond your current maximum. Once you have obtained all Sacred Orbs, Haja will let you enter the hot spring for free, but you will no longer be able to overheal.

Glossary Entry
