Sheen of Ice

2nd-level evocation (winter)

Casting Time: 1 action
Range: 60 feet
Components: V, S, M (water within a glass globe)
Duration: 1 minute

A small icy globe shoots from your finger to a point within range and then explodes in a spray of ice. Each creature within 20 feet of that point must make a successful Dexterity saving throw or become coated in ice for 1 minute. Ice-coated creatures move at half speed. An invisible creature becomes outlined by the ice so that it loses the benefits of invisibility while the ice remains. The spell ends for a specific creature if that creature takes 5 or more fire damage.
