Decided to not stick with Dragon Talon for bosses and just let merc clear it.
These dropped and decided to throw away my kicker boots without any usefull stats except 25% crushing Blow

Going back to town and load up on Thawning's

Actually a really easy fight. Had to go town 5-8 times (don't remember) for pots or just to safe merc.
Tactic:
1. Cast Life Tap
2. Move away and cast Town Portal to safe merc if needed at the last second
3. place 5x Lightning Sentry (3K ish dmg)
4. Recast Shadow whenever.
Took some time, but never that difficult
