I'm adding cinnabar (and later, other mercury-related things) and I wanted to add some kind of "mercury poisoning" to these items. The idea is that every 20 seconds, a player holding cinnabar has a 10% chance to receive Poison II for 10 seconds. I've been looking at Extra Utilities' Unstable Ingot, which causes the player holding it to explode 10 seconds after it's been taken out of the crafting grid. However, RWTema hasn't updated it to 1.15.2, so I'm not sure how it might work now. Any ideas?

Keep in mind that a lot of the concepts from previous versions can still apply.

In the case of extra utilities, it save the item's creation time to NBT, compares it to the world time, then uses PlayerTickEvent to blow up players who have expired ingots in their inventory.
