What is the cap for -armor?

What is the cap for -armor, I mean the physical armor not magic armor.

[AboveThis]

there is none

or atleast not reachable

[SjuwkPacient]

This is not wow and why would there be an armor cap for non "tank" heroes anyways?

[Vahn]

Well the forumla ends up with as you get to a really low armour (-1000 ish) you'll get near -100% reduction which is double damage.
You can't get more than -99.99999% reduction but the actual number of armour has no limit in either direction.

[Vida]

What holds the armor value? integer or double? and is it signed or there's another variable indicating that?

[Vahn]

I have absolutely no idea, ElementUser probably knows though.

You can try to find out by adding the most armor reducing heroes in one team, equip them with the armor reducing items.

I'll go with: Pestilence, Demented, Armaddon, Panda and Andromeda or SS which give the same, that gives:
15, 30 (with Scepter), 3*5=15, 8, 5 = 73 armor reduced.

Add to that a shieldbreaker and a daemonic breastplate, 6 and 5 so equalling 84 in total and that should be the lowest you can reach since 0 is the lowest base armor (Pebbels?)

Edit: You can take Predator instead for -6 armor on lvl 16 ult, or kraken which also has -5 for the last hero.

cd alone can do -50 armor and basically unlimited minus armor if you refresh him.

edit: cd as in corrupted disciple, not as in cooldown

Probably a signed short int

-32768 to 32767

@haschisch: no, charges are of data type char (in this case a signed char) and it'll only go from -128 to 127

[UrienRakarth]

what would that do to incoming damage?
