Screwing around with some people in Discord, we came up with this lol:
Starfall Coronet
+4-6 to Core skills
+100-150% Damage to Burning Enemies
+25-50% Meteor Size
5-10% Damage Reduction to Burning EnemiesMeteor now has 2 charges with a 5 second Charge Cooldown instead of a mana cost, and afflicts enemies with Apocalypse for 10 seconds. While afflicted, critical hits from Pyromancy skills is converted into a Meteor that targets Nearby enemies. Burning damage is converted into Meteorites every 2 seconds.
