I decide being that I only have about an 1/8 of life left to take out some small mobs with whirlwind in hopes I would get some health globes as my potion was on cooldown, success. Now to deal with the red fire ball things flying at me that negates armor. I take out the minions one by one, then slam an Earthquake down with the molten type rune. Then I start to WW and get massacre right about the same time I hit the champion one last time to death. Five stacks of NV and between the treasure goblin and champion I get several rares and blues, lots of gold, and an adrenaline rush.
I love chasing treasure goblins into packs of mobs including a champion pack and surviving.
