Pulling Poison Posies
“The forest's landtraps have reached maturity and begun releasing noisome pollen clusters in their efforts to reproduce. When taken into the lungs, the pollen can cause severe irritation, nausea, and in the case of extended exposure, even death. These vile seedkin must be dealt with before the entire Twelveswood is engulfed in a cloud of despair!
— In-game description
Pulling Poison Posies is a level 20 guildhest introduced in patch 2.0. It intends to teach basic dungeon mechanics.
Guide
Toxic Battrap
The end boss of this Guildhest is a poison-spewing plant called Toxic Battrap.
Every few seconds, Toxic Battrap spawns a purple puddle on the ground, which will poison all players standing in it. Periodically, adds will spawn. Damage dealers should quickly kill the adds before returning to the boss.
Tank Mechanics
The Toxic Battrap and most adds will spawn inside toxic puddles, so the tank should take aggro (preferably with a ranged attack) and kite the enemies out of the puddles. Make sure to face the boss away from the party, but without placing the back of the boss in a puddle.
DPS Mechanics
Do not stand in the toxic puddle longer than necessary - this will make it much more difficult for the healer to keep up.
Always defeat the smaller mobs first before returning to the boss. If the boss is below 10%, focus DPS on the boss and ignore the smaller mobs that spawn.
