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.

Strategy
Toxic Tamlyn
More than a Feeler is a guildhest that requires the players to kill a malboro 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) and Acid Bubbles (purple bubbles). The bubbles will flow outward from the water. If the blue bubbles are not destroyed, they will spawn adds called Rotten Jams. The purple bubbles will explode when they collide with any rocky surfaces. When the purple bubbles explode they will damage and poison all party members nearby.
Players should destroy the blue bubbles and avoid the purple bubbles. Toxic Tamlyn has a Bad Breath attack that applies status effects and debuffs to all targets in a cone in front of him. Everyone except the tank should avoid the front of the marlboro.
- Destroy the blue bubbles and avoid the purple ones.
- Avoid Toxic Tamlyn's frontal cone AoE breath attack.
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.
