I still cant help but think that when something hits harder than a angry Anakite on its charge, then perhaps its offensive potential should be considered a little closer.I think the problem with the rhyhorn and rhydon is more tat they're a bit too tough. Dropped their protection and Berseker a bit and now they seem to suffer significant attrition.
I also though of a custom item for Onyx/Golem.
Lave Blood Argumentation. cursed, and gives fire shield. Likely con 4 as the shield. 5 fire/10 earth.
In case it should be possible to thug golems. I tried a bit. But its kinda hard to make them killy enough.
