I own a full set of Lordly Plate (Milanese Plate, Plate Mittens, Cased Greaves, Milanese Sallet). I got a shit ton of armor. Let me tell you this: it is not the OP suit of tanking stuff everybody believes. It works very well against AGI chars, because they bounce on most strikes, but against balanced chars, you can maybe take 2 hits more, and against STR based, 1 hit (compared to the medium armor I usually wear).
Also, the upkeep is horrendous. I am still on the same gold amount I was two generations ago, just because I wear the full plate once every four or five rounds. The suit of armor alone costs more than 55k gold.
