Right now, the element of arcanium cannons is set to one of the magics you are currently using. This means that if you’re not a magic user, or if you have a magic that’s bad for cannons, your drop is just worth less.
Instead of that, have them be “unattuned” by default. You could then go to an alchemist, who could then attune them to one of your current magics.
In my Merchant Ship Buff suggestion (srry idk how to hyperlink) I briefly mentioned the idea of NPC’s that could change arcanium attunement. It was mainly a silly and specific idea, just like dyers, but it could be useful for this suggestion. If it doesn’t make sense for an alchemist to do this, then a medium-rarity NPC on merchant ships can do this just fine. Also I’m getting the impression that magic attunements actually affect the stats of the cannon/ram, which worries me but idrc since I like it when my ship has the same magic as me
Now I’m curious, did you find this on the trello or something?
