Currently its a bit annoying going off and doing something, coming back and still not having metal infused, it would be a nice addition to have a rough idea of how long left in the infusion.

Upon (now actually being able to) testing myself, i got results of like 0,14 charge per tick during night times from collector crystals in shrines. Adjusted the required charge to be much lower, so that this becomes actually feasible...

Edit: I think adding a method to see it, defeats the design idea.
