More than a Feeler
“A massive tangle of vivified briar and vines known by the locals as Toxic Tamlyn has taken root in Fool Falls and is poisoning the water which flows into the Nym River, and eventually down to the Rhotano Sea and Limsa Lominsa. The morbol must be slain before the city-state's entire freshwater supply is contaminated, but to do so will require entering an area churning with deadly bubbles that release noisome fumes and bloodthirsty denizens of the deep.

Guide
Toxic Tamlyn
More than a Feeler is a guildhest that requires the players to kill a Morbol boss named Toxic Tamlyn.
In the fight, the malboro summons bubbles from the depth of the water. The bubbles are divided into 2 types:
- Stale Bubbles (blue bubbles) - If these are not destroyed, they will spawn slime adds called Rotten Jams.
- Acid Bubbles (purple bubbles) - If these collide with any rocky surfaces, they will explode, dealing damage and poison to anyone nearby.
Players are intended to destroy the blue bubbles and avoid the purple bubbles. However, most groups in Duty Finder will simply ignore all the bubbles and burn the boss down, as it's faster.
Toxic Tamlyn also has a Bad Breath attack that applies status effects and debuffs to all targets in a cone in front of her. Everyone except the tank should avoid the front of the Morbol.
Healer Mechanics
In the event that multiple members of the party are hit by the breath attack - the priority for heals and esuna in this fight is: healer, tank, dps.
Heal the target once before cleansing the debuffs. After the debuffs are removed, continue to top off the target. When running low on MP, use 
Lucid Dreaming to regain MP.
