Akja

You transmute the ground around you into a pit of lava, except for the ground beneath your feet. Creatures that are in the area, start their turn there, or enter it must make a Dexterity saving throw. On a failure, an affected creature takes 4d6 fire damage and falls from a height of 10 feet. While in the lava, a creature takes 3d6 fire damage at the start of each of its turns. On a success, the creature can move to an unoccupied space within 5 feet of the pit.

At Higher Levels. When you cast this spell by spending Mana points equal to a 3rd-level spell or higher, the fire damage increases by 1d6 and the radius increases by 5 feet for each spell level above 2nd. At 5th level, the fire damage becomes incinerating.
