Prerequisites: The ability to cast at least one ice spell
You gain the ability to turn areas of water to ice.
If it is raining, you can use an action to cause the rain to fall as sleet in a 4-meter radius cylinder centered on you. If it falls as sleep the area is lightly obscured and the ground becomes covered in slippery ice for 1 minute. A creature that enters the area or ends its turn there must succeed on a Reflex saving throw or fall prone. You can end this effect on your turn (no action required).
If it is raining, you can use an action to cause the rain to fall as snow in a 4-meter radius cylinder centered on you. The area is heavily obscured and the ground becomes difficult terrain for 1 minute. You can end this effect on your turn (no action required).
You can move across any water surface as if it were solid ground as your steps create ice patches on the top of the water for 1 minute.
