Frostbite

Frostbite  is a status condition similar to poison that is given to players during certain puzzles taking place in the Greater Deep section of the God Wars Dungeon; however, it can also be inflicted by the Zamorak godsword's enhanced special attack. Jagex has stated that they will release more Frostbite-inflicting things in the future.

It works similarly to Poison, except that it is much more deadly, as it deals damages more often. It can be cured by drinking some Hot soup.
