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.
