The way mez works here is simple.
Dazzle works on Bz mobs cause they 50.
GoK works on Baz mobs cause they 55 (spawn when Bz mob is killed).
Rapture only for Biz cause they 60, but you shouldn't mez him cause only one anyways.
(FYI use rapture on first mob, then tash, youll see GoK workin fine)
Least i think last two are correct, was just there all weekend, burnt out on the place atm, might have biz and baz backwards.
If you have 2 59+ chanters (Im 60) this is cake. With only one, we had to camp after first cycle, keeping the original two mobs mezzed (Bz), and killing the cycle off third one (Bz dies, two baz spawn, Baz dies, Biz spawns). We'd then repeat the cycle on second mob, keeping add bz mezzed.
This is definitely the hardest part of PoA. Spirocs are cake, I was only chanter and kept 7 mezzed no problems. These bees are nasty tho.
Make sure when you pop the named (two named bixie level 63, has DT - he spawns after all the wasps are dead) you either A) camp a cleric right away, or B) wanna give up his spawn cause he depops after 80 min. OH YEAH, TRY to get him near a hill cause our melee couldnt hit over half theyre attacks were spaming too far to target cause hes way in the air.
Hope that helps ;).
