Requires attunement. Allows you to instantly attune to an item, without having to wait an hour. Occupies one attunement slot, as well as the item you are instantly attuning to, taking two slots in total. You have a general knowledge of how to use the item you instantly attune to, but you’re not 100% sure what all it does. If you attune to a sentient or cursed item, you make any checks the DM asks for at time of attunement with disadvantage. You can learn what the instantly attuned item is capable of as you use it over time.

But wait! There's more!

Using InstAttune, you can attune and unattune to an item in minutes. Can only attune to one item at a time. Attuning takes an action, unattuning takes an action, and requires concentration to do either.

This was mostly just a fun concept I came up with, I haven't actually used it in a game yet. I think it was kind of inspired by Grog in CR 1, and how he attuned and used that cursed sword without asking hardly anything. So I decided to make an item that could have added to chaos.

I'm open to suggestions, or just add a comment on how you would use this item!
