I have a unique, self-created problem in that I have amassed 1,600 mage amulets that I need to turn in.

It would be wonderful if there was a "Turn In All" option that turns in all the amulets in your inventory (or, like, 100 amulets, if we want to limit it) and converts them to shards/tomes en masse. If it needs to be limited by type of amulet, that's fine too. Anything that makes turning in quicker than individually turning them in. I'm sure there's other areas of the site where this sort of QoL change might be useful too. :D

Full support.

I hate turning in mage amulets just a few at times because it always feels more successful to do a bunch at once because it feels like you get more from it. I know statistically you don't, but it always feels better getting 10 tomes rather than one or two. But, yes, its very annoying to turn in a lot at once.

I'm thinking something very similar to how the fragmentizer works. Check off a bunch of amulets, then let the system run.
