The Healer is a group of 5 small healing tools, it has two types item healing and three types spell healing.

The unique secret of the Healer is how to edit properly the priority tree:

If the priority is 'Item': the healer will run in this order: Heavy Item → Light Item → Heavy Spell → Mid Spell → Light Spell

If the priority is 'Spell': the healer will run in this order: Heavy Spell → Mid Spell → Light Spell → Heavy Item → Light Item

To active a heal tool you must check the 'Light' or the 'Heavy' for Itens and 'Light', 'Mid' or the 'Heavy' for Spells.
