Lately there have been a few posts complaining about Irk. Some say OMG its impossible to kill, and others - meh not that bad. To make things easy on my key farming, I took my peace mage. The first Irk was a bit tough, but after 3 or 4 minutes of EV's with some energy bolts he went down - no brain. I thought, ok, that is doable. The second Irk - holy crap. Not only could I barely dent his hp, but he magically seemed to heal what little damage I did in a few seconds of him oblitterating my 2 EV's. After many attempts, I simply gave up trying and had to resort to taking him to the fairies at that entrance. For many of the ML named, there are average and super versions of them. Swoop and Miasma are this way. Throw in the changeling template on a tough version and it can be a lot of trouble.
