Ice Shields
"Gives troops around the hero temporary shields that absorb damage until destroyed. Excess damage from the hit that destroys the shield is negated."


  • Ice Shields is a Hero Ability that Dr. Kavan can use during attacks.
  • When used, Dr. Kavan creates ice shields on every nearby troop, as well as Critters and himself. These shields have low hitpoints but negate excess damage.
  • The health of the shields deplete over time.

Offensive Strategy

  • You can use the Ice Shields to have your troops survive an attack from a high damage defense such as the Boom Cannon or Doom Cannon, without being destroyed or taking serious damage.
  • Using the Ice Shields ability can protect Zookas from being destroyed by Mortars or Sniper Towers.
  • The ability is ineffective against defenses that deal continuous damage such as the Flamethrower since the low damage per hit means that the Ice Shields only serve as extra hitpoints; they negate little damage.
