@Dreamingheart it actualy increases your weapon delay. Might be a glitch, or just a hidden effect. Eisen Grip had that too back in the days, and it was a glitch.
The tp gain won't factor into price. This glitch has happened before on eisen grip, and it was promptly fixed. We can expect this one to be fixed as well. No one is going to pay millions for something that will be worthless in a month or 2 after they fix it.
Adds aprox. 42 delay to your weapon. Depending on what you're using, it can easily knock you into a 6 hit (for non-sams) without even trying. I'm surprised this isnt selling for several mils seeing what a massive effect it's having on TP gain.
