Jolly Co-op is probably my favorite feature of this game. But after farming Twinkles, Chunks, and some Larges, I'm SL120 on NG with the Hollow, Ash Lake, Catacombs, ToG, and the Kiln left to go. I always try to spend my souls before heading into dangerous areas. But even after sinking a ton into things like Dragonslayer Arrows, I end up having a bunch for leveling.
Now I'm at the point where I'm Co-oping with folks on NG+ or better, if I can find anyone at all. Is it time to recognize the greater availability of souls and adjust SL expectations upward to account for it?
