I talked a tad about that in the comment above, but I didn't use it except on gloams and archers. I'm very very far from a curses expert, so correct me if I'm wrong, but dim vision wont help once the merc engages them right? I suppose it would help him not get swarmed though. Is that the idea? But I used decrep most all the time. Drastically reduced merc dmg taken, gives me plenty of time for positioning, and increases the effect of CE enough that I don't really need to switch to amp (on p1) before starting a chain. I'm trying to get better though, so I'd love to hear your thoughts on how and when to use dim vision.
