K, so I know I’m new here, but I believe I found something on the Collector that could save some time. I found a way to get hit while the boss is doing it’s laughing thing, which will allow you to hit the boss and knock it down one time. In order to do this you only need the mothering cloak and the mantis claw. When you enter the arena of the collector, they don’t spawn right away. You need to jump onto the wall that is above you when you first enter the arena, dash after you jump off of the wall, and then dash immediately when you hit the ground. You should dash into the hitbox of the collector, and you should get hit. Then, you can hit the collector enough to knock them down once. A side effect of this is that the laughing particles will still be around the collector, if you knock them down fast enough. I don’t know if this was already known, but I haven’t see anyone do it. This glitch could help in all grubs, 100%, 106%, and 112% I believe, and I think it could save around 15 seconds.
