This mod takes inspiration from another mod called requiemmod by ladysnake.  Instead of only fighting mobs, you can become them. By using the Possession Relic, you can take control of many different creatures and gain their body, size, sounds, movement, and special abilities. Each possession feels different, so becoming a spider, guardian, hoglin, blaze, wolf, slime, villager, and many others changes how you move, fight, heal, and survive.

To get started, you need to find Possession Relic Shards:

These can be earned through the Soul Trader Shrine, a special structure that can be found in Dark Forests, the Deep Dark, and Soul Sand Valleys.  Activating the shrine starts a wave-based fight, and after clearing the shrine, a Soul Trader appears and offers shard-related rewards. Shards can also show up in bastion chests.

 Once you collect enough shards, you can combine them into the Possession Relic and start taking over mobs.

The mod adds a lot of custom possession behavior. Many mobs have their own attack styles, movement rules, sounds, healing foods, resistances, and special traits. Some can climb walls, some can fly, some can swim better, and some have unique attacks like beams, rams, fireballs, stings, or spit. A lot of forms also change how other mobs react to you, so some creatures ignore you, some protect you, and some become hostile on sight.

The goal of the mod is simple: turn mobs into playable forms and make each one feel closer to how it works in vanilla Minecraft, while still giving the player a new way to explore, fight, and survive.

For more in depth information on each mobs:

MAIN PREMISE

- Craft a Possession Relic.
- Use it on supported mobs to possess them.
- While possessed, you take on that mob's body, camera height, sounds, health style, movement, resistances, and special actions.
- Many mobs also change how other mobs react to you. Some ignore you, some help you, and some target you on sight.

You can get shards from:
- Soul Trader Shrines
- Bastion chests

The Soul Trader Shrine is a custom structure that can generate in:

When a player gets close, the shrine starts a 3-wave fight. The waves must be cleared one at a time. After the final wave, the Soul Trader appears on the altar and offers shard-related rewards.
