So Rhubzard has this mechanic that can plunder a weapon, and then it becomes useless and there's no reason to keep using it. However with DEX's lean shift I can use that mechanic to my advantage, because with a plundered weapon you'll barely hit Rhubzard, and as a result I gained a lot of BTH.
After that I start stacking bleed with lovestruck caliber + master archer's bleed skill for even more bleed. I probably could've switched out the shark pet for underwyrmling towards the end to avoid the SP attack, but I wanted to make sure the bleed didn't fall off.
