Sounds Over POwered

And I have it

What dungeon did you run to get it

WHy

waddles int a dungeon, *clink*clink*clink* alerts everyone in a 6 mile radius from the sound of screeching metal.

"It's still technically a successful stealth mission if no one is alive at the end."

How so?

Resistance cuts damage in half 

Plus it only works on non magical attacks by the time you get this most things will have magic

You have resistance to nonmagical damage while you wear this armor. Additionally, you can use an action to make yourself immune to nonmagical damage for 10 minutes or until you are no longer wearing the armor. Once this special action is used, it can't be used again until the next dawn.

So... could you use this action to prevent yourself from taking falling damage? The description doesn't match the notes.

I mean, falling damage IS nonmagical.
So as long as your activated it within that 10 gap of hitting the ground (really I doubt any fall will take longer) then yes, you shouldn't take that fall damage.
Gives me ideas for a cadre of spelljammer setting attack troops that jump from orbit in these suits.
Just casually landing on their feet in a city and annihilating the inner defences.

I'm reminded of a line from one of the Halo franchise novels about their Orbital Drop Shock Troopers regarding when the "parachute" for their drop pods malfunctions and doesn't fire or becomes detached before it can slow the descent. The line was something to the effect of "They'd be digging their own grave shortly."

Getting back on topic, nullifying all nonmagical damage is pretty overpowered. I would limit it to damage from nonmagical weapons, and let the DM interpret whether or not it would work for things like falling or being crushed by rocks etc.

This is a legendary item, it is not "overpowered". you could deal with someone who is wearing this in a thousand different ways. 

There are plenty of ways to deal with immunity to nonmagical damage.
Like magic for example. or magic weapons. Or enemies that deal magical damage with their attacks.
It's a legendary item. It is meant to be powerful.
It's not overpowered. It's a legendary item that is strong af for the very limited niche it fills, especially when it's obtained at higher levels, where enemies use magical damage anyways

Really good, but really hard to get

… yes... but as stated below... it doesn't stop any magic. so any spell still act like normal which by the time you get this... is pretty much everyone

at firsti tought non magic resistance isnt that op by the time you get a legendary item

then i realised usually in dnd you arnt fighting people you are fighting beasts or traps ...wich are almost all non magical damage

to be fair might just be my dm

 This is a good point.  Dragon-fire may be magical, but it’s claws likely aren’t.

Also, as earlier commenters pointed out, negating environmental damage is a big deal, when you plan on fighting Ifrit in the City of Brass, or take on Ice Devils on their home turf.

how to get this magical Armor 

It's a Legendary item. By the time you get it, EVERYONE and their mother has magical weapons

Can It be made out of adamantine combine celestial steel

I'm using a legendary weapon, as my starting weapon because I plan on the difficulty being cranked up
