Ash, the Glacial Sorcerer

When you play a Water Spell - You can place an Ice Wall counter on target non-destroyed Tower you own. (Towers with Ice Wall counters get +500 defense. If a Tower is destroyed, remove all Ice Wall counters from that Tower.)

Remove all Ice Wall counters from all Towers you own: Deal damage to target Unit equal to the number of counters removed x500. Each copy will display its serial number out of the total print run.
