I happen to have a pretty much perfect Zodiac Shield...
Armor is 16 (max)
req9
Health+27 (only 3 hp less than max which is nothing for a warrior)
5 dmg reduc (20%) <<MAX!!!
So yea...pretty much perfecto!
How much are you willing to pay exactly for this shield? Remeber: this shield is a rare drop, and to get it with these mods is absolutely lucky! So its gonna be expensive.
