Create Avatar

The Avatar is a 'grown' creature inside a growing vessel.  One or Two vials of blood need to be prepared.  The first vial will be the blood of the transferring creature that will be using the Avatar.  If a second vial of blood is prepared, the creature grown will be the race (or combination of races) of the blood in the second vial.  The vial(s) are placed in a prepared chamber/vessel with a seal-able lid during the initial casting of the spell which will take about 8 hours.  The construction cost of this chamber should be at least 3,000 gold pieces.

The new creature (race based on blood used) forms inside the chamber used in the spell’s casting and grows to full size and maturity in about 30 days; you can also choose to stop the aging process at any time once an age appearance you desire has been reached.  (This is done by the Wizard who casts the spell and not by opening the container).  The sex of the creature is determined at the initial spell creation of the Avatar.  The Avatar remains inert and endures indefinitely, as long as its chamber remains undisturbed.

The final process at the end of the initial 8 hours casting time is to 'attune' the transferring creature to a single gem worth at least 5,000 gold pieces.  At any time after the Avatar has matured (Avatar will automatically stop maturing at 18 years old equivalent for creatures race) the transferring creature will touch the gem at the same time they place the Avatar's hand (or equivalent) to the gem and the transferring creatures 'mind, spirit and/or soul' will 'transfer' to the new Avatar.  The transferring creatures body instantly dies after transferring to the Avatar.

If the transferring creature unattunes or breaks the gem, they will no longer be linked to the Avatar.  At this point the Avatar might still be used, but this would require a wish to make it happen.  If the chamber of the Avatar is breached, the Avatar will expire and no longer be usable after 24 hours.
