When you start concentrating on the effects of the spell, roll 6D10, these are the number of meteors you can summon each hour the volcano is active, they fire out randomly in a specified direction, the rate of fire is up to you. In addition, if you create a volcano on certain minerals or metals, it may augment the damage or effects of the Volcano, these include:

Sulfur: Ash generated by the volcano deals an additional 2D10 poison damage.

Metal, higher grade than iron: Meteors deal an extra 4D10 bludgeoning damage.

Magical effect: The meteors and lava gain the effect of the magic in process, but only in terms of damage, this effect is only applied on spell effects that are permanently in the area.

In addition lava starts flowing from the volcano until the next stage at a rate of 10 feet per round, it deals 18D10 fire damage on touch, or half as much within 15 feet of the lava. You may start summoning meteors from the volcano at this stage of eruption

3 Hours: The volcano erupts again, dealing 25D10 Thunder damage to all beings within 300 feet of the volcano, or half on a successful Con save.
