From The Pokemon Insurgence Wiki
Sleet is an ability exclusive to Pokémon Insurgence. It is the signature ability of Mega Cryogonal.
Sleet summons and increases the damage of hail. Pokémon that are not immune to hail damage are damaged for 20% of their maximum HP at the end of each turn while Sleet is active. Sleet's effects are removed when Pokémon with Sleet are no longer on the field or hail stops. If hail stops but becomes active again while a Pokémon with Sleet is on the field, Sleet will immediately begin modifying the damage of hail.
Outside of battle
Sleet has no effect outside of battle.
