I believe they're talking about various attempts at using the automatic defences on the ruined temple in the underdark as a means of killing the minotaurs, by luring them into the attack range of the turrets.
I was, I probably should have been clearer
I was wanting to see what was able to be done with the fort/temple defences, and the minotaurs are the only viable target, I think. It took me a long time to figure out how to deactivate the defences, and I'm still not happy with such a permanent solution, but that's aesthetics.
I wasn't sure I'd be able to lure the minotaurs back, and the first time I encountered them I died a bit and crashed a bit so know that they are there helps to plan an approach. On the other hand, there are many encounters which are helped by planning, and could we be made more survivable with a bit of scouting before hand, without getting too cheesy.
One of the oddities of this particular encounter was that the automatic defences just stopped working after the first minotaur was killed. The second had not actually joined the battle because it had never gotten aggroed. I'm not sure when the defenses stopped working and I might poke at it a bit to find out, but they did not fire when I grabbed the second minotaur. The first was lured in with an imp, on the ground that it might not die with the fire when it came back to the gate. The minotaur jump to the gate and killed the imp (and gate) then walked away. As it walked away it got stuck in the defence auto fire, but as not other character was in the combat, everytime it lost enough hit points it auto healed, and because it was under fire it couldn't path back its home spot. So there was a heal / get hit cycle.
(I expect that this heal cycle is to deal with some of the cheesier attacks where the victims get hit by something they can't see, and that doesn't start the combat queue, so that you can't just snipe at something with an invisible imp. I've also been caught by it attacking Ragzlin from the rafters, when (for some reason) stealth was successful, and so combat did not start. Warlock stands up, force blasts DR, gets hide in shadows success (presumably 'cos dark) and the damn'd Hobgoblin just heals. I'm not sure when that started happening as most of the earlier games I just got caught sneaking around up there. )
On the whole the minotaurs aren't that hard to deal with, unless unlucky, if you know that they are there or scout to look. The bulette can make the scouting a bit tricky. (though it did once take out most of the minotaurs for me in an early game)
