--- Comment #6 from jeppe winther jeppewinther@gmail.com --- Retested with Wine 2.9, still didn't crash from fighting the mentioned monster.
The easy way to access said monster is to find (or buy) a Clutching Talisman, drop it on the ground and get a monster to run over it and pick it up, thus getting the "Clutching" affix.
These Talismans were part of the Talisman League, which was recently made available again for a limited time as part of the Legacy League. Once the Legacy League ends with patch 3.0.0 in June or July 2017, Talismans, and thus this type of monster, will again be unavailable.
In short: cannot reproduce bug as described, need more details, and in any event, trigger for bug will become unavailable again within ~30 days of writing this.
