I don’t think 1:50 is doable with the current route, it’d require too much RNG to go your way. I’ll probably push until I get a 1:51:3x ~ I’d be happy with that.
The drop mod is a mod that changes the drop rate for Imperil and Magnet to 100%. The VK mod is a mod that changes the rendering pipeline from Direct X to Vulkan, which makes the game run smoother.
