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 available for Dr. Kavan starting at level 2.
  • Ice Shields project an aura centered around Dr. Kavan, adding them to every troop (including himself and Critterss) within its area of effect.
    • Shield hitpoints constantly deplete over time or when they come under fire. If destroyed, any excess damage from that hit is negated.
    • Only one layer of Ice Shields can be active on any troop at any given moment. If the ability is reused, any troops with shields will have them reset instead of gaining another layer.
  • Each use costs 8 more Gunboat Energy than the previous, with a starting cost of 6 Gunboat Energy.

Offensive Strategy

  • Ice Shields are best used against point defenses that rely on dealing massive amounts of dmaage in a single hit, such as Boom Cannons or Doom Cannons. This is particularly relevant for large units like Tanks and Scorchers, buying valuable time for them to get around or destroy these defenses. Rapid-firing area defenses like Flamethrowers however often whittle down the shield quickly with numerous weak hits, negating their main advanatage.
  • Frail units do benefit from Ice Shields, as it applies to any number of troops. Zookas and Laser Rangers are notable examples given how Mortars can wipe a whole group of them at once
  • Before unlocking Pvt. Bullit and his first ability Taunt, Ice Shields can be used with Warriors in order to get temporary additional protection from defensive buildings. Since the Warriors' attacks are quite fast, Ice Shields will be able to improve their survival during the time they destroy Headquarters.
