I have three questions about item crafting:
1) Is there any advantage to using high level items in recipes? For instance, you need a hot edge (of any level) to make a searing edge. Is there any difference between using a level 10 hot edge and using a level 1 hot edge to make a searing edge?
2) Can you variant stack? For instance, can you have one Ash of Agni with 5 unique variants on it?
