Strategy for shaman soloing +6 dragons

[commongood]

Howdy folks,

Was looking to tick another box on the old bucket list and solo kill a +6 dragon.

I have full spell book and decent-to-meh gear including epic (my resists aren't great).

I was told that Ayilish and Entariz were soloable but when I read about their stats (hp, dmg, aoes etc) and compare them to some of the solo stuff I've done so far (cliff golem, 22 in a4 for instance) it seems rather daunting.

Could someone walk me through how a successful fight vs these two dragons would go? (How to / where to pull etc)

And maybe enlighten me if there are other +6 dragons that are soloable by a shammy?
