Gustav's Blizzard is Frost first and damage second: it slows everything inside it for five seconds while shielding your heroes in the same area. He has the largest mana pool in the game at 150, so he casts rarely and the cast has to matter — position it where the enemy front line will be, not where it is.
A hero climbs C → B → A → S — 3 upgrades in all. Every stat rises at the same rate on every hero, with one exception: the primary stat of the class rises three to four times faster. For Gustav that stat is Mana regen.
| Stats | Per rank | C → S |
|---|---|---|
| Health | +12.5% | +37.5% |
| Defence | +8 | +24 |
| Attack | +6 | +18 |
| Magic | +6 | +18 |
| Attack speed | +5 | +15 |
| Crit | +4 | +12 |
| Mana regenprimary | +4 | +12 |
Health rises as a percentage of base health; every other stat is a flat addition. The specialization is chosen at rank B, and the class modifier pools open at A and S.
Create a Blizzard for 5 seconds. Each second, inflict 2 (+1 per 8 Mana Regen) Frost and deal 15 (+50% Magic) damage to enemies inside the Blizzard. Shield Heroes inside it for 10 (+75% Magic).
A hero unlocks one of these at rank B. The choice is locked for the run, and it decides which role the hero ends up playing.
