Firetamer

As a bonus action, the firetamer can transform into a fire elemental. While in this form, the firetamer cannot cast spells, but can expend a spell slot as a bonus action to regain 1d8 hit points per level of the spell slot expended. When the firetamer is reduced to 0 hit points, falls unconscious, or dies in this form, it reverts to its humanoid form. It can remain in flameform for up to 5 hours, and can enter flameform twice, regaining expended uses after completing a short or long rest.

The firetamer is a 9th-level spellcaster. Its spellcasting ability is Wisdom (spell save DC 16, +8 to hit with spell attacks). It has the following druid spells prepared:

• Cantrips (at will): druidcraft, mending, produce flame
• 1st Level (4 slots): cure wounds, faerie fire, longstrider, jump
• 2nd Level (3 slots): flame blade, heat metal, lesser restoration
• 3rd Level (3 slots): daylight, dispel magic, protection from energy
