This is a quick encounter that will be over in 2–3 minutes and hinges almost entirely on keeping the tank alive through web spray. You will need one tank. The tank should pull Maexxna near a wall and face her towards the center of the room, the raid should position themselves behind Maexxna. Ranged DPS classes will be on killing cocoons. At the 30 second mark Mages will need to be on top of Maexxna to frost nova the Maexxna spiderlings. At this point the raid needs to AoE them down within 10 seconds before Web Spray. If any are left alive it is likely they will kill someone during it as they attack very quickly. Healers will need to apply abolish poison and all of their heal over time effects on the tank just before Web Spray. It is advisable to stop DPS at ~33% and wait for a Web Spray then blow all cooldowns to kill Maexxna so that she never does a Web Spray while frenzied which will likely kill the tank.
The tank will want to pull Maexxna to the leftmost suspended block, and then turn her around so she faces the opposite block. Melee DPS should stand behind her and the ranged DPS and healers will stand further away. When the fight starts, make sure shamans set poison cleansing totems down, otherwise the other healing classes need to dispell the poisons Maexxna casts. Designate 1 or 2 DPS to monitor when she casts Web Wrap and to subsequently shoot the players out of the webs. Designate another DPS to snare the spiderlings she summons, either use a mage with frost nova, or something like a death knight to aggro the spiderlings as they come. Make sure the spiderlings are killed quickly as Maexxna casts web spray just after summoning her adds. Healers need to watch for poisoned targets, as well as topping the raid off before web spray is cast. She soft enrages at 30% and is easily killed after that.
The ability that wins or loses this fight is Web Wrap, cast at the 20-second mark. Unless players can direct their pets to attack the Web Wrap, players will get sent to the wall during the first cast and stay there for the remainder of the fight. To defeat Maexxena before she casts web wrap, players must deal at minimum 125K damage per second in 10-player mode, or 380K damage per second in 25-player mode. More DPS than this minimum will be required, considering ramp-up time at the beginning of the fight.
