Lava Burst

You create a 90-foot-long, 5-foot-wide line of magically erupting lava. Creatures in the area must make a Dexterity saving throw. On a failure, they take 8d6 incinerating damage and end up with pieces of scalding rock stuck to their bodies, losing half their movement and having disadvantage on their attacks. On a success, they take only half the damage.

Removing the scalding rock fragments requires an action and a successful Medicine check. If a creature tries to remove the rock quickly without making this check, it takes 4d6 incinerating damage.

At Higher Levels. When you cast this spell by spending Mana points equal to a 6th-level spell or higher, the incinerating damage increases by 1d6 for each spell level above 5th.
