[Item] Idea for an Armor item

[Valiens]

An idea how to add an interesting armor item. Toggle item, with short cooldown, about 5-6 seconds which increases your armor, but decreases your maximum health, in a way that your effective HP against physical damage is increased, but against everything else you are weaker.

Interesting, but I fear it may be too close to Stoneskin - trade a debuff for armor with a toggle.

Technically yes, but the Idea was to create an Item which is very good for specific situation, for example if an enemy team consists of mostly physical damage you would buy it, while Stoneskin armor is not really a reaction item, you don't buy it because you see that an enemy team has something specific since it is as good against physical damage as it is good agains magical damage.
