That's an interesting idea. For the druid, I'd probably have the amulet automatically cast barkskin on the druid whenever they shift into beast shape (once per long rest), and have the item require attunement. Animal companions would be a little more tricky and harder to balance, I probably wouldn't even try unless there are already rules in the campaign for animals wearing armor.I'd prefer something of more general use to beast companions and druids in wildshape.
No, it's *exactly* what I would expect.Again, sounds right but doesn't work well within the 5E framework.
Again (very roughly) only Wizards benefit from this, and the only benefit is they can skip Mage Armor.
Hardly what you'd expect.
Point remains: AC works in really specific ways in 5E. For more, I refer to my earlier post.
With my house-rule, any class that could already wear light armor could still use it, but it would hardly be worth it...it would be a highly-situational thing, like needing to appear unarmored when undercover or something. But if you can already wear armor, you definitely should! However, classes that can't wear armor would benefit the most from this item. They would sacrifice a valuable magic item attunement slot for the ability to wear a type of "light armor" that they wouldn't normally have access to.
This is exactly how I would want the item to work at my table. Some players really want to be able to stack numbers into their armor class, but I'm not one of them.
