Grinding HR Brachydios. The guy is actually really fun to fight. I have one issue with him though, and it's a pretty big issue. In the rewards screen, this guy gives squat. I break both his pounders, I never get the pounder in the rewards. I break his scalp, I get one every other kill. After killing him and breaking everything, I get like 3 items from the rewards screen that are from him. then there's the random hard armour sphere and rare skarab.
I think he gives so few rewards because of the occasional shinies left over by his slime puddles which may make up for it. But I only ever get tears and the occasional slime item.
In HR you have a chance of receiving the following in the rewards:
Break his horn: Brach Scalp - 76%, Brach Carapace - 24%
Break his wrist: Brach Punder - 59%, Mystery Slime - 27% and Brach Ebonshell 14%
You've got an additional 20% chance for a Pounder if you capture as well.
