So I just wanted to point it to all that might have missed it, we got confirmation in TLM by Telsin that F-tin can store pain. This is huge, as it makes (as far as I know) F-tin the only feruchemantic metal that can be utilized in a non-end neutral way. There’s nearly no reason to tap pain once it is stored, so you can easily throw out your painmind once full.    Once again solidifying the absolute absurdity of F-tin.
