In addition to the Eschalixir (+1, +2), Nolan sells for beads, other Escha related items could be offered. Two examples would be Vulcanite Ore and Eschite Ore. There could also be a requirement to obtain these items, simply killing a NM that drops them. This offers more avenues to obtain these type of items. All Escha related items could potentially be added also, such as Ashweed, Duskcrawler, Void Grass, etc...
