Damage/Effect
Fire
The creature that damaged you is momentarily surrounded by green flames. It makes a Dexterity saving throw, taking 2d10 Fire damage on a failed save or half as much damage on a successful one.
Using a Higher-Level Spell Slot. The damage increases by 1d10 for each spell slot level above 1.
* - which you take in response to taking damage from a creature that you can see within 60 feet of yourself
It's a nice touch that the flames are green, gives it a sort of personality.
What happens if you die from the damage? Do you still cast the spell
No, you can't take reactions when you're dead (or unconscious).
Its funny that this spell has more gas than Divine Smite does now, but at the same time, has to compete with Shield, which is mechanically way better to the point you're not going to use this over Shield 99% of the time.
Using a Reaction vs Attack Action, plus Bonus Action (which is your entire turn) is a hell of a design choice.
Wait a minute, Now Enspelled items are overpowered
Why?
Now that you can cast the spells gained through your species with your own spell slots and your choice of spellcasting ability, using your lower-level spell slots on this as an Infernal Tiefling Wildfire Druid seems great with Enhanced Bond.
