I believe the 50 Polished Scales is too many for what it's worth, the Sacred Vial is 60 scales and as much as I want to upgrade my accessories, I see more value in the Sacred Vial with the price being so close, even more so with the Darkstorm Necklace costing 2 Dragon Tokens for a single upgrade. I expected this accessory focused event to be promising but it has soured on me, I would've jumped at it had the price been half at 25 but I don't expect a change in price to occur.
I apologize if this seems silly but I just had to vent and get this out.
