Ok so here's the plan with the whole group split thing.
I tried to split the group and balance it out (somewhat), and I understand the vagueness of the two groups.
The crypt group will be going into the crypt and killing whatever's in it and actually getting the goods within it. This group needs to be careful with how they do the diving into the dungeon and getting that stuff done. This group needs to be calm within the dungeon and they'll have their own encounters separate from the surface. They'll get less loot from unique characters that I have planned out for their encounters, but they'll get first hand at loot within (provided there is any).
The surface will meet a few more characters and will get better loot from those characters I have planned for their encounters. One of them is a goblin inventor that will have a cartel of random crap (be it metals to meatbread), and another would be a possible tribal chieftain. This group can be as reckless as they want, but they need to remember that the crypt is to be protected, and if stuff gets in, the plot I have will change.
I didn't want to split the group up, but it'd be a clusterfuck otherwise if everyone went into the crypt. Any questions about it?
