Stage 5 of the John Van Caneghem Tournament

(Leave 5 units of goblins, each with one member, and the 6th unit – a single centaur – with Goshak). The centaur is needed so that, with the help of reinforcements, the hero can attack several times. Goshak defeats the Cavern Dwellers (1 goblin remains) and, without picking up anything, moves to the right towards the Necropolis. I don't quite understand; can someone explain how, with 5 goblins and 1 centaur, you can defeat about 8-9 Cavern Dwellers (aren't they level 6 demons?) They cast Destruction while I'm running around with the goblins. Goshak manages to attack a few times, and the ballista fires, but it's clearly not enough. 2wolf64, please write down the battle tactics:smile45: Added after 10 minutes Also, please decipher all the abbreviations and clarify the names of some monsters, for example: Orcish Warriors – is this an upgrade? (not Warlords)
