Duration: Concentration, up to 10 minutes

This spell transforms a willing creature’s physical form into magical lava. For the duration, or until it falls unconscious, the target gains the following capabilities and limitations:

• The target has immunity to fire damage but vulnerability to cold damage.
• Nonmagical poison and disease can’t affect the target.
• The target has resistance to nonmagical bludgeoning and slashing damage.
• The target’s melee attacks with unarmed strikes or melee weapons deals an extra 1d6 fire damage.
• A creature that touches the target or hits it with a melee attack while within 5 feet of it takes 1d10 fire damage. If the target touches a flammable object that isn’t being worn or carried, that object ignites.
• Most gear melds into the target’s new form, but any object in hand when the transformation occurs remains in hand and is unharmed by the target’s lavaform for the duration. The target retains passive benefits from melded equipment, but can’t activate, use, or draw forth any of its melded gear.
