My guide to fight elites when solo for Monks, in Hell:

1) Find a nearby portal.
2) When found, walk back to the Elite, lure them near the portal
3) Hit the mobs, heal yourself with Breath of Heaven and pots, cast Mantra of Regeneration (rune is up to you)
4) When HP is low again and you have no pots/BoH to use, enter the portal.
5) Heal yourself again with BoH, wait for another 5 seconds before exiting.
6) Go out, hit hit hit hit again (remember to have a mercenary [templar/scoundrel/enchantress])
7) Rinse and repeat until enemies are dead.

DoT? the green thingy that they cast? And i use the lashing tail kick to knockback. then go in front whack whack whack then go hide again. hehe
