Para-Elemental Plane of Ash

Ash. Miles and miles of it. The air is poison and visibility is low, to put it mildly. The Great Conflagration is the intersection of Fire and Air. The deeper one travels into this plane the deeper the pile of ash gets, until they reach a pit without a bottom.

When dealing damage with fire or thunder, or casting a spell that creates or controls fire or air, choose if that effect is empowered or heightened as though those metamagic features have been applied to them. The number of dice you can reroll is determined by your Intelligence modifier (minimum of one).
