I was thinking (dangerous task, I know) and figured it was a pretty good idea to have a thread where people could post up what epic forms they have, what they're after, and so on. Getting the formula and skill for it is a pain in of itself, and I've found that making the item once you already have the form is decently easy.
Currently, I have the Reklar Tail scale form.
4 Ilithium Bars
2 Taravist Crystals
3 Epic Scale Cores
1 Plague Essence
is what's required to craft it. Feel free to poke me if you have enough stuffs and I'll happily make it for anyone. Will update here as I acquire more forms. If you have a form of your own, please add it, as well as the required components.
