In my quest to finish as many of the mage tower challenges as I can, I knocked over the Guardian Druid challenge a couple of months ago but forgot to post it here… so here.
People may find this helpful because it’s how I did it without Luffas – which would make it quite a bit easier – or tier. Gear wasn’t very well itemised, just a collection of the highest ilvl items I had from Mythic + dungeons. For legendaries I used Ekowraith, Creator of Worlds and Soul of the Archdruid. Took me a bit of trial and error but got it done in 14-15 attempts total.
Guardian Affinity was pretty important to help push damage on the Inquisitor in phase 1 without getting too many stacks of the healing debuff. Wild charge can be a life saver, if you get knocked back a quick charge back in can save the attempt.
In the end I saved Incarnation for phase 2, when I popped everything and tried to burn down Kruul as quickly as I could.
Definitely at the stage where even alts are starting to out gear the Mage Tower challenges so it good time to give them another try if you haven’t done them already.
