• Sleet. A 10-foot radius sphere, centered on the target, is covered in snow and ice and counts as difficult terrain for the duration.
• Humid. The target’s speed is halved for the duration of the spell.

At Higher Levels. When you cast this spell using a spell slot of 3rd-level or higher, the lightning damage increases by 1d10 for each slot level above 2nd.
