Hi,

is it possible to script, that a specific merchant got better sell prices for his goods? Let's say this: Every time the script is fired, the vendor reduces 1% of his sell prices. But it should be just a specific NPC merchant, not all of them at once. And for sure, the changes should stick to a savegame.

if you wanted it to stick you would probably need to make a new global for each merchant.
seems impractical to me.

not impossible, just a very large amount of effort.
what would trigger the 1% delta?
thats an important point too.
