You draw a straight line on the ground (by keeping the button pressed). When you finish, each enemy in a 1m wide strip along the line takes damage. If the damage exceeds 25% of the target's max HP, then it is knocked down. The mana cost of the spell starts at 280 and grows with the length of the line.
