Item description:

Quick tutorial: You have stuff to kill easily, if you are hurt just eat a Notch apple.

The Deep End
Defeat an Elder Guardian: use the elder guardian egg in chest to spawn one, then kill it.

Great View From Up Here
Levitate up 50 block from the attacks of a Shulker: You need to go on top of the pillar in the middle with the shulker projectiles. Get all the shulker eggs from the chest, spawn some on ground. As you levitate, you want to spawn some on the pillar (you can spawn them on walls) so you dont run out of levitate effect. Try to keep the effect until you get up there, or it may void the trophy.

Change of Sheets
Dye your bed a different color. You have a bed and bone powder, use them in the craft table (go down with L2 for coloration)

Cheating Death
Use the Totem of Undying to cheat death. Just die while holding a totem. You have to die from a monster, not from fall, drowning etc... Unequip your armor or you will never die.

So I got that going for me...
Lead a caravan containing at least 5 Llamas. Take Lama eggs from the chest, and leashes. Spawn at least 5 lamas close to each other, and leash one.

Let it go!
Walk across the surface of a deep ocean by freezing the water with Frost Walker boots. Go out of the fortress, you already are on a deep ocean biome so you should get the trophy, if not just walk around on water.

Feeling ill
Defeat an Evoker. Take an evoker egg from the chest, spawn it, then defeat it.
