Yup, not overpowered at all. However, I do consider to increase the time it takes to swap crystals to put a limit to the 'I'll simply buy a dozen of those' mentality that they might create in some players.MarkB said:Bear in mind that greater Augment Crystals must be applied to an item with at least a +3 enhancement bonus, so that's potentially an extra cost compared to what you might normally have added to that armour.
