How long does it take to unattune to a magic item?

[col_impact]

Let's say I am fully loaded with 3 attuned magic items. I have a Ring of Spell Storing with 1 minute attunement that I want to attune to, replacing an attuned item. How long does it take to attune to that Ring?

1 minute? 61 minutes?

I believe when you attune to a new magic item it drops off one of your currently attuned items, so it'd take as long to attune to it as it would if you had nothing currently attuned at all.

Well, by RAW, no time is listed, therefore you can't actually unattune from an item. Hope you like your first three! :P

I agree with Dork Forge. Simple, clean, works.

So 61 minutes is the correct answer.

I wonder if Catnap could be used to quicken the unattunement.
