Rex Bone Costume

Turning a Rex into a skeleton

The Rex Bone Costume gives a tamed Rex a skeletal appearance in ARK: Survival Evolved and ARK: Survival Ascended. In the game's words: "This costume can be used to make your Rex look just like a skeleton! Spoopy!" The costume weighs 0 and stacks to 1.

Hunting skeletal Alpha T-Rexes

One source the ARK Wiki gives is a hunt. While the ARK: Fear Evolved and ARK: Fear Ascended events run, Alpha T-Rexes spawn looking like skeletons, and the costume is in the loot of one that has been killed. The wiki's notes for that hunt:

• every skeletal Rex is an Alpha, so come ready for an Alpha fight;
• killing other creatures met along the way makes room for more spawns and so improves the chance of finding one;
• a costume obtained this way is kept after the event has ended.

Crafting and the ASE achievement

The wiki gives two more ways. During the ARK: ARKaeology event the costume can be crafted in a Cooking Pot. In ASE, finishing the Master Explorer Achievement unlocks it, and after that it is placed in your inventory each time you respawn. The wiki lists 221.0 as the version that added it.
