or soul stone
Well, these abilities fit better with the Reality Stone, but I think the Soul Stone has too few abilities, so maybe one of these could go there—or maybe not, and both could go to the Reality Stone.
The abilities are:
Clone Summoning:
In the KubeJS Discord, in the example scripts section, there’s a script that enables clone creation and offers some distinct advantages:
If the player changes form using a render layer, the clone will appear using Palladium’s render layer—unlike the other method. Additionally, each clone has its name tag and collisions, which can be seen by pressing F3+B. The downside is that it can cause some lag, but since it's tied to a single stone that exists only once per world, it's not an issue for around 6 to 12 clones.
Player Sushi?:
In Infinity War, there's a moment where Thanos, using the Reality Stone, turns Drax into sushi-like cubes. Something similar could be done by launching an invisible projectile at high speed. When it collides with an entity, that entity would be given a power like target_sushi (or another name). The entity would then lose the ability to move or jump, and their entity reach and block reach would be reduced. After a certain amount of time—or after X ticks—the power would be removed. As for their model, the player's model could be hidden and replaced with a pile of blocks on the ground using the player's texture—possibly even with an animation at the start of the power, where the blocks fall to the ground.
Below, I'll include something very similar to this, but it's for Doctor Strange's chains.
