@Komari that sounds pretty reasonable to me. The flash-buffs being more generic makes it a lot more versatile, but, it's still kind of limited, so the increased damage is a good idea.

@LThesaurus Yea, that make sense. I don't plan to throw the idea out completely, but to combine all the 3 items into one, so that they take up less of the loot pool. I'll also buff the flat damage the item gives a bit to make it more appealing, even without the synergy

There are so few sources of Flash-buffs that I feel like the transfigureds that add Flow-buffs are just so situational that they're not worth thinking about.
