Avatar of Shoth

You endow yourself with the power of Shoth, tapping into the many consciousnesses of the Ooze hive mind. Your body takes the form of a slime being of the players or DM's discretion and until the spell ends you gain the following benefits:

• You may upon casting this spell use up to your proficiency bonus in hit die to gain temporary hit points equal to the number rolled plus your Constitution modifier.  As long as these temporary hit points remain you cannot lose concentration on this spell. If any of these remain when the spell ends, they are lost.
• As a bonus action you may make two attacks with your slime tendrils using your spell casting modifier.  The attack has a range of 10 ft and upon a hit the target takes 3d6 Acid damage. A target wearing non-magical or natural armor must make a Constitution saving throw against your spell DC. Upon a failure the target takes a -1 penalty to their armor class or nothing upon a successful one. A creature with natural armor regains its normal AC upon the completion of a long rest. Non-magical armor that takes up to a -3 penalty is destroyed. 
• You gain a flying speed equal to your walking speed.
• You become immune to the Charmed condition as well as Acid damage. 
• You have gain advantage on Wisdom, Intelligence, and Charisma saving throws.

Immediately after the spell ends, you must succeed on a DC 15 Constitution saving throw or suffer one level of exhaustion.
