Notes As mentioned, Frost Man has 40 HP and his weakness deals 3 damage. 3x13 = 39, so you need a 40th point of damage. A single flash bomb lingers long enough to hit Flash twice. You can have two on screen at a time, so save your second explosion for his jumps around the room, or gets knocked back from a Flash Bomb. If done well, Frost Man will always be immediately hit when his invincibility frames run out.
