A blast of pure arcanic and volatile energy.

Its colours depend on you and your characteristics.
It is 65 ft/20 m long & 1,6 ft/50 cm wide.

You weave 3 circles of runes, each for a complementary purpose:
.The 1st gather and generates the energy.
.The 2nd shapes and stabilize it through rotations.
.The 3rd discharge it by giving it a linear direction.

 You inflict 3d12 of Force-Piercing-Thunder damages.
Thanks to the drilling motion, your beam will pierce through energy and matter until you hit your target.

 If the target fails their Con save, they are repelled backwards for 12 ft/4 m.
If they succeed it, they are able to stay where they are.
