I want to know what exactly the difference is between a Heavy Mage Robe and a Light Mage Robe. I get that light raises aspd and evasion while lowering def and mdef, and that heavy raises def and mdef while lowering evasion and aspd. But what about cspd? Is it enough to make a difference? Is it a bad idea to lighten mage robe? I'd like your input.
