Tramust's Volcanic Induction

A vertical cone of earth with a 15ft radius rises from the ground with a tumultuous upheaval. Creatures in the area must make a Dexterity save, taking 6d6 bludgeoning damage on a failure and half on a success. The area becomes difficult terrain, which remains when the spell ends.

Lava oozes out of the top of the formation, in four streams. Roll a d8 for each to determine which direction they flow, starting north going clockwise. Creatures in the path of the lava may use a reaction to move to an adjacent space before the lava reaches them. The lava streams extend 20ft radially from the center, and deal 6d10 fire damage when a creature enters it or starts their turn there. The lava cools and solidifies when the spell ends.

As a bonus action on subsequent turns (not including the casting turn), you can have two meteors fire from the volcano. Each can target a point up to 30ft away and deal 2d6 fire damage in a 5ft radius, and creatures can make a Dexterity save to take half damage.

At Higher Levels. For every 2 higher levels, the cone radius and lava stream length increase by 5ft, and the initial bludgeoning damage increases by 2d6, and an additional meteor can be fired on subsequent turns.
