Your ability to harness the power of the elemental plane of earth has increased dramatically. You gain the following benefits-

• You gain a burrow speed equal to your walking speed and can burrow through solid rock or other material leaving a 5 by 5 foot tunnel in your wake.
• Your strength score increases by 1 to a maximum of 20
• Once every long rest you can summon a mephit to aid you in battle. The mephit appears within 30 feet of you as a bonus action. The mephit is a dust mephit, a magma mephit or a mud mephit. Regardless of its type the mephit is friendly towards you and obeys your commands. It disperses if you summon a new mephit.
