The hard part is very much trying to DPS a princess down while tanking 3 and killing chimeras as they pop out the portals. Used lingering sloth on monk to keep everything on me since its super aggro (unlike the better versions that suck for aggro).
got the sleeves and pet class cloak last night, she was hitting 5004 max on me undef. is an awesome encounter. the portals were not destructable like the agnarr ones .
Queen fight is much like the king fight. You start the event by pulling 3 of the 6 princesses. When the princesses are pulled they will each spawn 1-3 chimara model mobs. These are mezzable. And like the king event when you start the fight bombs will start targeting random people (1-2 at a time came out of portal) and going up to them. Once the reach their target you have roughly 5 seconds to get out of the AE range. AE range is very short. The AE is a 5k RESISTABLE nuke. Best strat is to just let the bombs hit their target and heal groups. once you kill the first 3 princesses the next 3 charge right away. They also spawn the chimaras and bombs. Once the next 3 princesses are down the queen becomes active. She will aggro anyone who sets foot in her room. She hits 5kish dont think any AE's and she does enrage (duh =P). Queen is a push over compaired to haveing to deal with princesses.
PS. Chimaras don't teather, princesses and queen do. You can leave the room inbetween rounds, rez up (watch for bombs aggroing people that are draging others out) and go back in, but the chimaras will respown when you aggro the princesses again.
