SYSTEM NOTE: FIRE SPIRITUALIST
Your god is fire and your gift is keeping people alive. It sounds contradictory until your allies charge into battle juiced and literally burning. Please extinguish anyone who has stopped enjoying it.
Parent class: Cleric
Feature levels: 3, 6, 17
Features
Level 3 — Hearth Magic
Aid and Lesser Restoration are always prepared.
Level 3 — Channel Divinity: Spirit’s Shelter
As a Magic action, expend Channel Divinity. Up to three willing creatures within 30 feet each gain Temporary HP equal to twice your Cleric level + Wisdom modifier.
Level 6 — Juiced
A creature receiving your Spirit’s Shelter can immediately use its Reaction to move up to half its Speed without provoking opportunity attacks. Its next weapon or Unarmed Strike hit before the end of its next turn deals an extra 1d6 Fire damage.
Level 17 — Trolled
Spirit’s Shelter can affect six creatures. Each also regains HP equal to your Cleric level.
Notes
The fire theme emphasizes support and recovery rather than making this another damage-only caster.
