The Frost Mage chills up to two enemies with each bolt, slowing them 60% for 3 seconds while dealing 8.75 damage to each. It aims at the un-slowed enemy closest to your base, so it spreads its chill across the wave rather than piling onto one target. During a match you use it to drag the whole advance to a crawl, which keeps enemies inside everyone else's range for far longer. Its own damage is modest; the value is the time it buys. It is best when the team needs more shots on a fast or heavy wave before it reaches the base.
On a team: The Frost Mage controls what reaches the base. By slowing the front of every wave it multiplies the number of attacks the whole team lands, so every other tower effectively hits harder.
Base attack
The three kits

Frost BoltFree default
Chilling two enemies at once
Frost Bolt is the free default Frost Mage kit: a bolt that hits up to two enemies for 8.75 each and slows both 60% for 3 seconds, aimed at whichever enemies are not yet slowed. It spreads its chill across the wave, which is exactly the class job of buying the team more shots. Its spells are Ice Block, which freezes two enemies solid for 3.75 seconds and deals 76 to each, and Shatter, which deals 65 to each of the two enemies closest to your base. The loop is to keep the front of every wave crawling so the whole team lands extra attacks before anything reaches the base.
Frost Bolt: Hits up to 2 enemies for 8.75 damage each, slowing each by 60% for 3 seconds. (8.75 damage every 1.15s, range 12)
Spells: Ice Block · Shatter

StormcallerUnlockable kit
Forking lightning that stuns
Stormcaller is an unlockable kit that swaps slows for hard hits and stuns: lightning strikes the target for 9, forks to three more enemies for 4.5 each, and briefly stuns everything it touches for a moment. It still delivers crowd control, but as short stuns spread across a group rather than lasting slows. Its spells are Howling Gale, which slows up to two enemies 80% for 4 seconds and deals 40 to the first, and Static Fork, a clean forked nuke that deals 110 to the main target and 55 to up to three more with no stun. This kit trades the Frost Bolt's steady chill for bursts of damage and stutter-stops.
Chain Lightning: A lightning bolt strikes your target for 9 damage, then forks to up to 3 more enemies for 4.5 each. Every enemy struck is briefly stunned (0.85 seconds). (9 damage every 1.35s, range 12)
Spells: Howling Gale · Static Fork

Water MageUnlockable kit
Single-target control that drags enemies back
Water Mage is an unlockable kit built around one enemy at a time: its current deals 22 and drags the target backward at half speed for 5 seconds, walking it away from your base while it stays immune to other control. Instead of a wide chill, this is powerful single-target disruption that can send a dangerous enemy the wrong way down the path. Its spells are Riptide, which deals 60 to the front enemy and shoves it four path-lengths back, and Geyser, which deals 90 and a brief stun to one enemy plus 27 splash around it. Where Frost Bolt slows the many, the Water Mage removes the one that matters.
Undertow: A single-target current, 22 damage every 1.85 seconds, that charms one enemy: it walks backward at half speed for 5 seconds, then trudges back, held off crowd control the whole time. Targets the enemy closest to your base. (22 damage every 1.85s, range 12)
Spells: Riptide · Geyser
Upgrades only the Frost Mage is offered
These draft picks are locked to the Frost Mage. Full details on the upgrades page.
- Cold Fury: A frost mage that turns assassin.
- Winter's Reach: Your reach grows by 50%, and every slow, stun, or charm you land also grips one enemy next to your target, even after a weapon swap. One extra target, never the whole pack.
- Shatter Mark: Enemies you slow, stun, or charm turn brittle: the next 4 hits they take, from anyone, each deal 50% more damage (credited to you). Landing crowd control on it again reloads the 4 hits. One brittle mark per enemy. While brittle, the enemy also resists slows, stuns, and charms 25% less.
- Deep Freeze: Finish them in ice: against enemies at or below 30% health, your hits deal +150% more damage, your slows on them become a 1.2 second freeze, and your stuns and charms on them last 100% longer.
Numbers on this page are the live base values from the game's content files; wave scaling and drafted upgrades change them in play.
