I think I have a scum-less method for Dragon Isles. Same strategy as VHoS, orc berserker prep taurog and tri-sword. Go hard convert every glyph, I think you'll be able to have a standardised battle against the matron. WHUPAZ on the first attack, then another attack, then your resists are smashed but 4 death protections from taurog will see you through.
I had to kill some popcorn to get the last death protection but now that I think about it I should have prepared one beforehand. Saving my prepped reflex potion could have worked too. Oh, I guess I could have saved a quicksilver potion as well, I don't usually prep those though.
Fight the mini-boss at level 6 with a mid-fight level up, then a couple of pots should down him. I needed my other pots against the poison dragons in the subdungeon.
I would have got warmonger if I hadn't accidentally picked up a LEMMISI
