Gravite is NOT the same as using Corrupt - it's exactly comparable to RC staves and FoG items, which may I mention, are minigame items, whereas DG items are obtained from a skill. As a matter of fact, the magic defense that the RC staff provides is greater than the str/attack bonuses that a gravite rapier / longsword have over their rune counterparts. There is a certain logic behind banning Corr items because they are not consistently obtainable, and are extravagantly expensive for the amount of time that they last. The same cannot be said for Gravite - as a skilling reward, they can be obtained by anybody, and the recharge cost is far from extravagant. But I won't say any more about it, as it probably isn't relevant. Make sure both sides understand the rules clearly, and train dungeoneering.
