Soul unleashed (Mythic Feat)

you have mastered your innate magical abilities, and thus have made it possible to channel the power of your soul into a spell.

twice per long rest, as a bonus action you may channel your very soul into a spell, the spell you empower will cost no spell slot, and can be cast at any level that you have access to. if the spell has a spell attack roll, add a +5 to that roll, and deal an additional 2d12 force damage. the additional damage is added to any spell that deals damage, if it is empowered by this feat. (this feat only effects one spell per turn)

DM note: mythic feats are created with the knowledge that these feats are very powerful and should only be given to players at a DM's discretion. Also great for dmpc bosses or bbegs'!
