This creates a freezing mist full of hail and larger chunks of ice that will heavily obscure the area and last until initiative count 20 of the next round. All creatures within the area of effect take 13 ({@damage 3d8}) cold damage and must make a {@dc 20} Wisdom saving throw or be {@condition blinded} until initiative count 20 of the next round.",

These immediately crash to the ground causing 14 ({@damage 4d6}) slashing damage to everyone in the area of effect (the damage is halved if a {@dc 22} Dexterity saving throw is successful). Afterwards the terrain becomes difficult and anyone falling {@condition prone} within it takes the damage again (no saving throw).",
