A solid 25% of Saint’s offensive power is in prebuffs, another 35% is in summons, and all the rest is in mind control, and he doesn’t have time to do the first two right now, if the whole party isn’t here I don’t see us killing/capturing four full fledged witches/demons without Killer being given free reign to sacrificd as many innocent people as possible which the others probably won’t let him do. Miguel being there might be a solid trump card though, even if we’ve forgotten about him...
Though even if we go for the witches I feel like they can call on backup pretty easily. We should probably honestly just leave, or do what Killer suggests and try to slip a tracking spell into their food if they order anything.
