How to play Frost

Wall with Chill. At 20 gold it is Frost's cheapest tower and builds in 1 s, so it is the brick your maze is made of. Lay the walls first, then put the stronger towers where the path folds back on itself.
Slow the path: Chill, Frost Tower, Blizzard, Frost Bolt, Glue, Permafrost, Frostbog, Ice Shot and Glacier slow creeps by 30% or more, so every other tower in reach gets more shots. Slowed creeps also regenerate at half rate.
Stun: Permafrost can stop creeps in their tracks for a moment.
Against flyers: flyers ignore your maze and head straight for the goal, so bring towers that look up. Ice Shot targets flyers first.
Against armour: Rime Shatter deals true damage, which armour can't reduce.
Ultimate: Glacier costs 600 gold at tier I and 2400 for its tier III upgrade. Save for it once the maze holds on its own.

Elements

Chill, Frost Tower, Blizzard, Frost Bolt, Glue, Permafrost, Frostbog, Ice Shot and Glacier deal water damage: 1.5× against fire creeps and 0.5× against nature creeps (bosses still take 0.75× from a weak element).

Sniper deals neutral damage, which ignores the element triangle.

Rime Shatter deals true damage, which ignores both armour and the element triangle.
