There are plenty of alchemy calculators out there, web-based as well as offline, most of them having an option to select ingredients you own and list potions/poisons available for you. I even created my very own just for fun =) The missing feature (mostly planned but never done by the authors) is the ability to actually read the ingredients in posession from a saved game. I would like to do so in my version. I used the description of TES5MOD format for saved games on UESPWiki, but did not understand the way the inventory is stored inside. Does anyone have this knowledge and can share? Or is there a more complete description of skyrim ess format? Regards, Maxim
