Expected Behavior

Corrail should not generate tombs for possessed entities.

Also phoenixes should be able to fly.

Current Behavior

When you possess an entity and die while possessed, a grave is created for your possessed entity with all of your belongings AND you will retain all of your belongings when you respawn right next to above grave.

Also, phoenixes can't fly.

Possible Solution

Make Phoenix Flight a thing!

I don't know how to fix the item duplication part. Sorry.

Pre-Requisites

1. Electroblob's Wizardry Master Wand with Summon Phoenix (or any animal) and Possession
2. Corrail Tombstone enabled to capture all items on death.
3. A can-do attitude

Steps to Reproduce

1. Fill up your inventory with a lot of diamonds, emeralds, nether stars, etc. Really, the world is your oyster.
2. Climb to a REALLY high place with a sudden drop that would kill you.
3. Summon a Phoenix with the Electroblob's Wizardry wand.
4. Possess said Phoenix with the Electroblob's Wizardry wand.
5. As the possessed Phoenix, attempt to fly before finding out that your vessel is nothing more than an incendiary turkey with a God-complex.
6. Splat onto ground and die.
7. Respawn surprisingly right next to where your flame-turkey has died (with tombstone) and ignore the world message stating that you've fallen out of this world (the rules of the spirit realm are so finicky).
8. Reach into your pocket to realize that your flame-turkey would not let you live on without your prized possessions.
9. Mourn your flame-turkey by right clicking on the Corrail Grave that marks the place where it breathed its last breath.
10. Allow the duplication of your entire inventory, including the core 4 clothing items you were wearing, to console the fact that you will never be a magnificent Phoenix flying across the sky. :_(

Detailed Description

Phoenix flight should have the flame particle effect and should resemble a self-propelled Elytra (when shift is pressed) with slow fall (rather than creative flight or actual Elytra). Kind of like the rending gale, but not as fast. You have to go a little slower to be a bit more showy.

Also, when your possessed being dies, you should come out of the possession with like slowness or something like that. Nausea. Like you were just brutally ripped from another beings body after using a necromancy spell. There has to be some negative side effects. Graves should also not generate.
