Well, I went in with my Ranger - AND COULDN"T KILL ONE DESTROYER
I lasted for several minutes (It used to take me about 4 minutes to finish a run), getting volleyed and spirit rifted like crazy = -29's everywhere and none dropped. It seems they have buffed the monster skill "INNER FIRE" to keep them healing regularly.
So, I tried in Normal mode - still with ranger - and killed one before the cycle started again. I survived for 1000 + spirit rifts but couldn't kill them.
SO, I added EoE (to add damage if I did start killing some ) and Predatory Season to reduce the effect of healing to the ranger - still no luck.
Tonight I will cap the elite skill Quicksand for my ranger- hoping this will cause some energy denial and maybe keep them from healing so easily.
Elite Nature Ritual. Create a level 1...8...10 Spirit. All non-Spirit creatures within its range lose 1 Energy each time they attack or use a Skill. This Spirit dies after 30...78...90 seconds.
