Not quick, but fun.
check out Ilsh's champ spawns (valor or humility) looking for a Vermin one.
Finish it, get the champ up, and he will summon lots of rats (archers, Mages, etc) as it takes quite a long time to kill the champ solo now.
I had my dragon on Barracoon while Lots of Rat mages casted on him, heh.
Lots and lots of vetting but not boring.
