Changes

Add a chance for a slime to give multiple offspring a helmet

Only happens if the drop chance is not 100%, meaning not items it picked up

Give slimes 4x armor and 4x protection

Since they are just a head, they don't need to protect other parts of their body, so the helmet is more effective

Give skyslimes a chance of diamond or emerald modifier

Need to implement something like tags for this in the future

Cap tooltip on prot. modifiers at 80%

Practically you should never reach that without changing limits, and the sum total cap is more important, but this is something

Reimplement self destructive using a potion effect

Automatically handles the ticking behavior, and makes it easier to apply to enderslimes later. Plus, visual indicator of explosion, both from your point of view and others
