Repair Cost

I went to see how much it costs to repair my bargain green beam swords and it's 6278 gold per point at 95%. But no way I see of changing it on the wiki. Oh one of my reforges gave one of my beam swords 1 level to max attack power but it suddenly makes the change in the swords max attack on the item itself?

Instead of base ~115 max it's showing ~117 instead.

1 max attack = 2 max damage.
