Well, where is what I came up with:
7 Mutated Dire Rats (Level 2)
Flooding Room (Level 4)
3 Mutated Bladelings (Level 2)
2 Mutated Goliath (Level 2)
3 Mutated Dire Rats (Level 2)
125*7*2 = 1750
175*2 = 350
125*8*2 = 2000
4150/4 = 1037 xp each
The game has been going for about 8 months.
Level 3: 2000xp 2032 gp
Level 4: 2336xp 2800 gp
Total Torqua, Haaku, and Leather: 3037 xp, 2032 gp
Total for Ilex and Fhangrim: 3373 xp, 2800 gp
We didn't earn any treasure in game, so our wealth may end up being a bit lighter than expected.
