Do you mean getting the mixer to overload and spray?
Or how it turns people into goblins?
Or are you seeing some combinations not make sense? Have you combined the eyeball with the grabber?
That’s Saber, a warrior.
If she had a crossbow (and not a grapple bow), it means she should have gotten just a boob potion and jiggle potion.
Butt potion is only for Thieves, characters in black or grey clothing, or characters you give a thigh potion to, who AREN’T fighting skeletons, so Saber would not qualify in this instance.
Now, if she had a grapple bow, which is a crossbow with rope, then you’d give her boob, jiggle, thigh, and butt (unless she’s fighting animated armor, in which skip the thigh and butt anyway, and if she’s fighting a skeleton, skip the butt but keep the thigh)
