Ok red skelly is 29th normally but have seen it 32.

There are GSkeles too 23-26

Monks and dark bones 23-25 ish <might be innacurate this though will be
close the top 2 are definitely right>

Trash zombies and skeles

Calm should be fine. I used druid harmony here easily. Get a sow before you
try. Use multi calms 2-4 if alot in spawn.

I say sow for 2 reasons. 1 you can semi kite it at 28th solo as long as the
res on your undead spells is not too bad. Also you can step back aways and
heal. Also if the calms go wrong and you get 2 just leg it outta there and
zone to feeroot and come back and try again.
