So using a rather custom party of 8 I ran the Mall of Doom solo.
After tabulating everything, some major totals were:
340 NPCs killed for a total of 5137 EF; including Kwong, 123 Moaners, 57 Mud Worms, 41 Reptilus, 9 Rubble Spiders, 42 Blood flyers, 24 med center robots, and 21 wolf frogs
Armor with a total average sp value (I use the average result of the sale price to determine the sp component of the EF reward) 27030.5. Weapons (including ammo) with total average sp value of 119460.5, and other loot worth 59803.5 sp. A total average sp value of 206294.5 sp. (I had some good rolls, especially with armories, but only 2 8-gauge shotguns and 33 shells). And that doesn't include the rewards that they were promised. In fact, because of the haul they did manage, the party is probably going to leave a bunch of stuff behind in Walsave to help out - they do not need it all.
In the end, there's 5137 EF and 206264.5sp to turn into total EF for the party. Using the revised EF table and calculations I found on the boards, that works out to ~1150 EF per member, or enough to bump them up to Rank 5 in one sitting. (Using the RAW, that's ~3200 EF/Rank 13!!)
It is me, or do the adventures seem to not match an expected increase in ranks?
Yeah, it's pretty out of hand. Then again, as a lure to draw the kids deeper into the fire... should work like a charm, right?
I'm soloing it right now and the loot has been fairly impressive. I think everyone is at Rank 2 but not Rank 3 since I'm using Rank Buy (reduce EF to zero after hitting new Rank). Still have the main wing of the mall to check out!
