Medic Hat

The Medic Hat is an uncommon head armor in the Nurse and Medical sets that converts the wearer's basic attack into an ally heal rather than damage, starting each battle with Damage Down 1 (which reduces healing by 1). Heals can critically hit for double value. Purr or Cleanse abilities remove the Damage Down debuff, effectively boosting healing output by 1 for the rest of the fight.

One caution: any status-applying effects on your basic attack (from weapons or mutations) still fire when healing, potentially inflicting debuffs on allies. Clerics also don't benefit well from this hat since their basic attacks already have their own primary effects that compete with the heal conversion. Best on classes with straightforward basic attacks that have nothing better to do than keep allies healthy.
