since it is sometimes for a morrowind character with alchemy skill to mass produce potions cause theres so many things to carry, I set up my own shop, and have found it to be very profitable.
1. find mark and recall spells. you can take the mages guild teleport to every mages guild until you find them. theyre about $150 each.
2. kill the owner of nerano manor in Balmoro- you wont get caught, and you can use his house for for lots of stuff. its bigger than caius cosades house (and caius has stolen my things in the past).
3. nerano manor will get robbed if you leave your stuff alone, even if its locked. so you need someone to guard your stuff. Hloromar Wine-Sot is good for this. Hes a naked barbarian outside of Caldera. tell him you'll help him, kill the witch for him, but DONT pick up his axe he wanted. he will kill you if you have it and dont give it to him. Instead, just walk back to nerano manor in balmoro. Just outside the manor, cast a MARK spell. Head upstairs to the bedroom. Hloromar will follow you. make sure you shut the door behind you so he doesnt get away.
You now have lots of room for weapons, armor, ingredients and anything else. Hloromar prevents your house from being robbed. But if you try to leave, he will follow you. so to exit you will have to use the RECALL spell, which will send you outside the manor to the place you marked.
the fine alchemist from white haven will give you good prices for your potions. if you have a masters mortar and pestle, your potions will be worth more. you can steal one of these from the mages guild in cladera on the top floor, or you can kill Aureone Fernis in vivecs foreign quarter and get one to spare, some rare ingredients, and lots of free potions and recipes. For some reason, no one in vivec seems to like her, and if you kill her you will only be fined $40. just make sure you turn yourself in AFTER you have ditched all the loot back at nerano manor, otherwise the cops will take it.
In the future, I plan to find the other 2 naked barbarians, lock them in my house too, and bring them along to fight for me when i need them. Just keep them in a different room then Hloromar, or else he will escape with them and your house will get robbed.
