Torrential Rain

You create a 20-foot-radius Sphere of heavy rainfall centered on a point within range. The Sphere is Heavily Obscured. It lasts for the duration or until a strong wind (such as one created by Gust of Wind) disperses it.

All exposed flames within the area are extinguished and targets within the zone become vulnerable to lightning damage. If they are resistant they take normal damage. This spell does not affect damage immunities.

Using a Higher-Level Spell Slot. The rain’s radius increases by 20 feet for each spell slot level above 1.
