I'm thinking that 4 pcs all chosen of malal wearing heavy armor and chucking explosives at each other would work, alugnment wise I mean. Play them as happy go lucky clowns that solve all their problems by running up to enemies and playing hot potato with grenades.

You're all teamkilling ftards so throwing explosives at one another is just good clean fun.

Really tzeench, cuthbert, raven queen, and vectron are all easy enough for your traditional murder-hobo type adventurer to run with no real dangers of alignment checks. For the real easy street pick vectron and put on a looped recording of ten/fifteen minutes of silence followed by you saying 'praise vectron!'. That should cover 99% of any alignment issues.

In a year of playing I think I called for 2 alugnment checks, and one may have been for an npc ally.
