Honestly, I would hold onto the money for now. +30% damage is 23 without affinity and 29 with affinity. Not bad, but not a significant increase. And you can’t enchant a weapon twice, although it’s not like you’d want to focus on that anyway. 150 rems isn’t exactly a fortune, but I think the idea of saving up for a better sword from the blacksmith seems like a more reasonable option.
