Did you fuse your Mastersword with anything?
And would a Drain Buster work on a Polygon Jive?
What about Doppleganger Staffs? Would they be useful for a quick distraction while you make a break for it or should one skip it entirely?
Monster House... That sends chills up my spine. I wouldn't know if it would be worth it to fight or just book it for the exit.
And I wouldn't mind using the Scroll of Removal on a certain enemy (Either that special someone in the Plains of the Sun or those Skull Mages you see near/at the Plains). And I'll be bringing a Scroll of Blessing if anything gets cursed; I'll make sure to keep those types of enemies away. Far away.
My epic Mastersword that I lost was fused with one of those swords that attacks three directions at once and was plated and was +53 or 54. I had a storehouse jar with me so I wouldn't lose it, I hadn't counted on being confused by one of those eyed bastards and I was beyond pissed off when it happened.
Doppleganger staff might work on the polygon jive, even better would be throwing monster meat if you have it. I've never tried a drain buster so I couldn't say how well that works.
As for monster houses, I always fight through them, the drops and loot are always prime.
And bring as many blessing scrolls as you can get your greedy mitts on. Another of my favorite tactics is to slap cursed stuff into a jar of change. Whatever new item you get won't be cursed and I've had this work out surprisingly well a few times.
