Azird, hate to break it to you but the slimes didn’t change any aspect of our spiral. We still spiral same rate and next world we will still spiral same rate and tbh we might even out spiral majority of the hermits and other players since they won’t know how to deal with slimes which causes more of a problem between faction and small villages/hermit gap. Slimes are annoying mechanic for people who just want to mine and even if they cause a problem, I just make more characters and swap them out. Slimes prevent botting which some groups did for mining and they did help solve the issue, but now they are highly unbalanced and could be balanced while preventing botting. There is way too much variation in spawn rates and tbh too much variation in the amount. Things shouldn’t be hard because they are spamming numbers and breaking the mine supports.
Also I usually don’t mine on 5 and before slimes still didn’t mine on 5. I usually mines 3-4 because there is no real point of 5 when tunneling. Also iron is iron, regardless if it Black ore, bloodstone, ect.
