had to recruit a new merc for this one. woljif wasn't cutting it as a grease monkey. This only took one attempt to record (and one trial run to test) - anyone says that Unfair is re-rolling for crits has never stacked pits, webs and grease. Also swarms seem to have eaten never-ending nerfs since release.
Merc is an Arcanist Phantasmal Mage spc'd for Conjuration - Arcanist for the +2 to DC from Potent Magic Exploit, and Phantasmal Mage for the Illusion Metamagic later on with Expanded Arsenal Mythic.
Additional thoughts: Conjuration CC and throwing axes don't work great - the range is too short. Might also re-spec Camilla to Ranged since that seems to be the name of the game early and Wenduag will be the only one ever ending up in combat hopefully. Also bring Protection from Arrow, Communal for this whole section.
