Klausbot

Klausbot was a reward in the 2018 and 2019 Christmas events. He has somewhat better speed than average for a hero, and has two different attacks: his normal melee attack with his axe, and a second frost attack which damages all nearby enemies. This second attack does 500 damage and happens once every 10 seconds.

When he was first released, some people felt that he was rather overpowered; see Commentary:Klausbot. However, with the release of other powerful heroes, he has settled into a role as a somewhat above average fighter.
