so I had 2 skeletons done regular
then I had 5 skeletons but their weapons and armor weren't broken
then I had one skeliton, no broken weapons and armor and I gave him one level of the NPC class warrior
then i had one flaming skeleton with no broken weapons and armor and with one level of warrior
so what i got was
2+5 cr 1/3 at 135 each = 945
1 cr 1/2 at 200 each
1 cr 1 at 400 each
total 1545
does this seem right? and would it mean that it counts as a CR 4 encounter?
they weren't all attacking at once but they were all in a house
to be more specific they fought two skeletons, then two more, then three, then the warrior then the flaming fighter. they only had one round between fights before they pulled the next set.
do I count each seperately as encountrs?
Medium skeletons?
2 standard Medium skeletons = 270 Exp
5 standard Medium skeletons with better gear (but not NPC level) = 675 Exp
1 Medium skeleton warrior 1 = 200 Exp
1 Medium skeleton with the Flaming template added = 400 Exp
Total Exp = 1545/CR 5 (1600 Exp)
As for separate encounters, that's a judgment call. Frankly I usually only count different encounters if the PCs have a reasonable enough time to not only heal/buff for next fight but also assess what's going on (use skills on the villains/environment, cast divination spells, etc). A 1 round breather sounds like one long fight where reinforcements came in a few rounds apart from one another.
