but magic attack does nothing on a defender... so essentially you are wasting rps on a templar weapon. That weapon is basically for bossing or showing off how you can go pos neg pos neg melee...

In any account if you are not sure about something, ask the gms first before buying it. It is much safer that way. While you can dispute them removing a purchase and get the rps back. They wont be charge rps, they will simply be genaric rps. So if you did buy with the charged rps I suggest only spending them on EM.

Side note EM needs to take from earned rps first before going through the charged rps, or have an option to choose how to buy like the IM does.
