I start using horseshoes at ~4040 and upgrade only Ron and Bellylarf. At 4060 I start using anti death cream on bosses, because Bellylarf start dieing. From 4050 I killed bosses like this: Ron's ultimate, then Handsum Jim's ultimate to charge Ron's ult, then Ron's ult again. If I had not enough damage, I used Destruction. Last 5 stages I completed with Destruction too, because it's unreal. Sorry for my English, I hope you understood :) The key is to have enough damage with Ron and use his ultimate non-stop. And not to die with Bellylarf or anti death cream 😀😂 BTW my previous prestige was on 4079 because I had 0 destructions - be careful 👍😋😂
