Alter Weather

You seize the air currents above you, taking control of the local weather. You must have clear sight of the sky to cast this spell, and the spell ends early if you end your turn unable to see it.

When you cast the spell, you can choose to shift the precipitation, temperature, and wind each by one stage on the charts below. It takes 30 minutes for the conditions to change, after which you can change them again. The charts suggest weather effects, and your GM may determine any additional effects resulting from the change in weather. Your GM may rule that fire or cold resistance, hot or cold weather gear, or other measures partly or completely protect a creature against the effects. After the spell ends, the weather returns to its original state, changing at the same rate. The spell ends if you cast it again or dismiss it as an action.

Precipitation

Higher stages include all the effects of lower stages.
