Hi! Tiaras for runecrafting would be cool I think. It would give further use to both silver and talismans, the latter of which is pretty moot once you have one.

It could work similarly to the talisman, using the tiara from your equip screen. This wouldn't be OP at all I believe, adding a single extra inventory space per trip. Plus, new runecrafting method, and a market for talismans.
