Well Seismic, with regards to luck you could always do what some ppl do... bring a luck suit with you, when the monster is dead or near dead, swap that one on before you open the corpse.
Luck is kinda like Bigfoot... people claim to have seen him... some say it's a myth. Some claim that you have to wear luck the whole time, some claim you can just put it on at the end when you open the corpse.
I know that getting arties now is different and you accumulate 'points' for each boss kill.
What you could do, to free up some points... Depending what your real/lore/taming is... you've always got a few talismans to choose from to get +10 points.
Mark of Travesty to get another +20
Tome of Lost Knowledge for 15 magery
Jewels (if these aren't already taken for something else)
Drop vet to 90 and use enhanced bandages (acts as though it's 100vet)
Leave Discord at 90, get a pair of +30 discord jewels, swap on to discord, then take off and throw other jewels back on.
That will give you some more play in skill...
However, for Doom, I do like having chiv on my tamer so that I can Remove Curse for the impaler who likes to moral wound your pet.
You could always do what i've thought for soloing Doom... for all the regular bosses, just any regular tamer template... then for the DF, have my sampire logged there to solo the DF. Then log sampire once done... go back to tamer etc etc...
