I was wondering if you could add different items other than wands to cast spells. Specifically I was thinking they would have different conditions of activation, like it activates if you hold it in your hand, off hand, equip it, charge it (like a bow/trident), etc. I was inspired by concepts from Mundus Magicus.

Sounds like an interesting idea

I originally wanted to have it work with dispensers (or possibly a custom caster block) as well, so ill likely implement that in one go once I refactor stuff internally to support it

Armor that triggers on hit for example is something I considered as well
