As an action, you can use the Dash action. Until the end of your turn, you don’t provoke opportunity attacks and you can move through other creatures as if they were difficult terrain, but can’t stop there. Each creature that you move through this turn must make a Fortitude saving throw.
On a failure, it takes 2d8 radiant damage.
On a critical failure, it takes twice as much damage.
On a success, it takes half as much damage.
On a critical success, it takes no damage.
You can increase the damage by 3d8 for each additional mana expended.
You can expend 1 additional mana to increase the damage by 1d8 and double the extra movement from your Dash.
