Vessel From The Multiverse

You tap into forces of the multiverse searching for a vessel to borrow.

Multiversal Vessel. You are able to abuse the forces of the multiverse to allow yourself to transform yourself into a separate character that matches your appropriate level. You have this character's HP, skills, spells, proficiencies, everything they have in the characters skill sheet. you completely turn into that character for 2 rounds in battle, or 30 minutes IRL time outside of battle. The caster may dispel this at any time it's active.

Knowledgeable Host. for the caster to successfully pull off this spell you must roll higher than the character's AC for it to allow you to use it's body as a vessel. If you fail the roll, you don't have any knowledge about the vessel. This means you roll with disadvantage for any and all actions. (ex: Initiative, attacks, spells, saving throws, basically everything)

Experienced Host. If the caster transforms into a character they have used before, they can bypass the AC roll and successfully transform ONLY if they were successful the first time. If you transform into a character you've used before and failed the AC roll, you must roll again to see if you roll higher than the character's AC.

Chained Vessel. You may exceed the time limit of the spell, staying the vessel of the character you're borrowing. However, exceeding over the limit forces a level of exhaustion on you. You gain a level of exhaustion each round you take after the limit, or every 10 minutes IRL time outside of battle.

Endurance. Every 4 levels, you gain 1 round and 10 IRL minutes out of battle time added to your exceptional limit without gaining exhaustion.  

Once this spell is dispelled, any active spells, items, etc. belonging to the vessel character will disappear. 

This spell can only be dispelled from the caster themselves or a being much more powerful than themselves. (Ex: a Divine God or being that transcends the multiverse) Discuss with your DM about this but also be fair.

This spell can only be used once after every long rest.
