Pyromancer

You have trained using fire-based spells as a weapon, granting you the following benefits:

• You spellcasting ability score increases by (if you use multiple ability scores for spellcasting, choose one of them to increase).
• Once per turn, when you deal fire damage to a creature with a spell of 1st level or higher, you can set that creature on fire. Until a creature uses an action to douse the flames, a creature on fire takes 1d6 fire damage at the start of each of its turns.
• When you score a critical hit with a spell that deals fire damage to a creature, you can roll one additional damage die and add the result to the spell's damage.
