You can use this jumping to your advantage. Position a character up in that stockroom area on a ledge but back enough that they are behind something. Have someone, meatshield, ranger pet, whatever, aggro the Minotaur and draw them into range of the other. Get their attention with that character, when minotaur jumps up on ledge, use the knock back arrow or maybe shove, the fall should kill them. The Bulette also can distract them, for me, it managed to kill one and I used the ledge tactic for the other.
