||On the East side of the arena. Standing in the Energized Pole causes the needle to drip and leaves a purple puddle on the ground below it for a few seconds. Standing in the AoE turns the player into a Gorilla, which is used for Bomb's Away.
||On the West side of the arena. Standing in the Energized Pole causes the needle to drip and leaves a red puddle on the ground below it for a few seconds. Standing in the AoE turns the player into a bird, which is used for Boost.
||Activates the Red & Purple Syringes for a few seconds. Damages and debuffs the player standing in the AoE. Shock Therapy is used after a player has stood in the AoE.
||Used when Ratfinx is normal-sized. Scatters Smartbombs around the arena. A player should use the Red Syringe to knock the bombs away with their skill, Browbeat, preferably into the far corner from the group. After a short time, the bombs will explode in a massive, heavy hitting AoE and apply a Vulnerability stack.
||Used when Ratfinx is giant-sized. Ratfinx pounds the ground four times, inflicting Vulnerability Up each time. Everyone should use the Purple Syringe to transform into a bird, which is necessary to avoid the ground pounds. Players should use Wing Cutter to deal damage to the boss while transformed and use Apothecary after the 4th pound to undo the transformation.
||A room-wide unavoidable AoE used after someone activates Energized Pole.
||Used when Ratfinx is normal-sized. The player with the red marker over their head should run to another corner (preferably not in front of either syringe) to drop the poison puddle away from the group.
||Used when Ratfinx is giant-sized. Hits the MT four times, inflicting headache for each hit. At four stacks of headache, the tank becomes concussed, stunning the MT and causing them to take increased damage. The boss will then wind up a long line AoE tankbuster. The OT should provoke when the MT reaches four stacks and take the tankbuster.
||Spawns random adds around the arena. Should be picked up by the OT.
- Gobbledygroper: should be tanked facing away from the group as it does frontal damage.
- Glassy-eyed Cobra: also does frontal damage.
