Instead of having lava at the bottom of the pit you can put 2 cactus diagonal, that way everything dies, just need to have the walls mined out for the cactus
I could be wrong or misunderstanding it, but I think the goldrush powerup is better since double drop at 5% gives the equivalent of 5% more drops, while the money gives the equivalent of 50% more drops once the items sell. And the double drop could proc on worthless drops while goldrush would proc on everything. Don't play the server and am just going off of the description of the upgrades though so you probably want to check if money applies to everything. Also I love the vids and #teamroyal
Money crystal might be worth if you can have your pick/hoe/sword in your off hand and sellwand in your main hand (like you did in Dungeons). Should give the boost when selling collection boxes.
