Arcane Beam

You fire a beam of arcane energy at your target. Everyone in a 60 ft line, starting from you, must make a Finesse Contest against Will. If you succeed, they take 2d6 Arcane Spell Damage. If you tie or fail, they take half the damage you rolled instead. For each additional Stamina you spend on this spell, add an additional 2d6 Arcane Spell Damage Dice.
