Armor pieces with the "illuminati" trait given by lumium don't trigger while the item is in your armor slot. Instead you need to hold it in your hand.

I apologise for the late reply, that would be a problem with the fact that I'm using the default traits the tool parts have instead of rewriting them for armor parts. Hopefully I'll be able to work on a fix for that soon.

I've noticed this for a handful of other traits. Slimy never spawned slime, for example.

Should be solved alongside #64

Can confirm- Illuminati triggers when armor is worn OR held- but for wearing, it only recognizes if it's on leggings. Not sure if that's intended or not.
