Bodyguard

You create a Bodyguard to protect yourself or another from attack. When you cast this spell, choose yourself or one person within 20ft of you. The Bodyguard protects only the chosen person, not anyone else. The Bodyguard is a Tiny to Large creature or construct that takes any shape you chose. It cannot be touched, and can move through any space, as if it were a wisp of smoke. It looks like a representation of the form you choose, but is wispy and blueish-grey.

The Bodyguard will follow the chosen person anywhere, and can breathe underwater as well as fly. It has AC of 14 + your spellcasting modifier, and an HP of 1d8 x half your player level (rounded down). It is fully aware of all danger around it, but cannot communicate in any way. When the player it is assigned to is attacked, it moves instantly in the attack's path and takes the full blow instead. The attack automatically hits the Bodyguard. If the attack requires a saving throw, it automatically fails.

If the Bodyguard is not destroyed by the attack, it continues to operate as normal, but cannot receive any healing from any source except if you cast the spell again to fully revive the Bodyguard. If it is destroyed and there is damage left over, it does not apply to the player the Bodyguard was protecting.

The spell can be cast again by the same player, and this either:

-Fully regenerates an already existing Bodyguard

-Creates a new Bodyguard that cannot be assigned to a player that already has a Bodyguard

-Makes an already existing Bodyguard protect a different player
