Question about Groddo's Armor...

Each piece has reduced dammage...

Does this have a commulative effect...

and can you still add runes...?

If not that is alot of cash to spend on looking good....

If it is commulative, and you can add runes this would allow for taking very little dmg.?

Or is it really just for looks for people with more money then brains..?

The effect does not stack, if you're talking about the Ascalon armor family. The damage reduction effect from one piece affects your whole body, so you only really need just one part to have the effect.

Yes, rune -damage does stack with the effect. Just one rune though.
