Campeón del Fuego: Quetzalcoatl

On activation, all of the caster's materials ignite. Lava flows through their veins, and their body ignites on fire. Steam erupts from the caster's pores, gathering with the fire and taking the shape of Aztec Warrior armour. This spell can only be unlocked with Quetzalcoatl's full trust.

-----------------------------------------

For the duration of the spell:

• All damage the caster does becomes fire damage. After hitting, targets must roll a DC 17 Dexterity save, or be caught on fire. 
• The caster gains a +2 to AC and + 10ft to movement speed. Furthermore, the target gains a 5ft flying speed.
• All locked spells by the Macuahuitl del Sol become unlocked.
• At the end of the caster's turn, they must take 1d6 fire damage.
• If this spell is active for more than 5hrs, it will become much more difficult to dispel this magic, and the fire damage will increase.
• In a 5ft square radius around the caster, the ground heats up, steams and may eventually crumble.
