D&D 5E Unarmored Defense as a Feat?

[Vael]

So, say this feat existed, is it too good?

Unarmored Defense
Choose an ability other than Dexterity. When not wearing armor and not using a shield, your AC is equal to 10 + Dexterity modifier + the chosen ability modifier.

It should be fine.

Mostly I see it being used as an option for characters that would otherwise have light armor, and would give them one or two AC higher than their non-magical options.

If you roll for attributes, its power could vary...

I feel like it is stepping on the toes of 2 classes and a subclass a bit too much ( Monk, Barbarian, and Bladesinger ). Straight up power-wise it is pretty powerful but shouldn't be game breaking in most cases.

I like it. Feels in line with the last batch of UA Feats. Also, my group is reskinning D&D as superheroes as an experiment so this is absolutely gunna be used at my table.

I'm going to make my usual argument that if it works at your table, go for it. Maybe you have a table without traditional unarmored classes - no barbarians, no monks, etc. Lets say a mage takes it - it doesn't stack with Mage Armor. As they've said before, all the various armor situations are kind of binary, yes-no ways to calculate. The cost of a feat slot means they won't be able to use that slot for a feat or an ASI, and since you only have a certain amount of them ever for your character, it's an interesting trade.

I do think an issue might be if this is something you were going to write up for a setting or additional material to be put into other's games. Personally, making someone take a feat to get part of another class' level 1 abilities seems alright. Even second edition had ways to build your class where you got to piecemeal a class together; I think even Greyhawk had it in their Adventures book when they talked about levelling up from zero- to first-level and keeping some learned abilities at an XP cost.

YMMV

For a whole feat, certainly. I might even argue for it being a half-feat.

As written, monks could use that to apply three stats to AC. Monks are MAD, so it's unlikely to be a large bonus, but it could be. I heard barbarians can apply Con to AC, but I've not seen one in play, so I'm not sure.

4e had this same feat, but forgot to make it a bonus feat for monks and avengers (who essentially had this as a class ability), so you could double dip that way.

In general I don't like the idea, because the numerical bonus is too "soft". Max +5, minimum ??? I think monks should drop the Wisdom bonus to AC and just start with a higher bonus instead.

 

[Paul Farquhar]

I wouldn't be concerned about it being too powerful, even on a wizard.

I think it lacks "flavour" for my game though.

 

[jmartkdr2]

I would take it for every Hexblade I played, but even for that I doubt it'll be seen as a a must-have option.

So yeah, that's a well-balanced feat.

EDIT: upon further thought, I'm not sure I'd allow Dex + Str. That's both very good for barbarians and makes belts of giant strength way more powerful than they already are.

This feat, phrased as is, wouldn't stack with either a monk's or a barbarian's Unarmored Defense. It would give you the option of using this formula instead of the class feature's formula.

It would be interesting for a Strength-based monk since it would let them swap out str of wis to AC. It would be a very strong choice for a barbarian, although I'm not sure it's better than GWM overall.
