Elementium actually has a lower vendor value as it drops less green gems / stack. Although there doesn't seem to be a final value yet, This post seems to suggest a drop rate of 4.4 green gems / stack, which would mean a vendor value of approx. 40g / stack. I'll either make a separate version for Elementium (very easy) or add it to the current one (quite hard) as soon as the Obsidium one is bugless and fully working, depending on public demand.And what about elementium ? How much is the prospected and cut average value? I sells like 35-40g max per stack on many servers now
