Boss 2 - Rádarríg

Rádarríg is a high-pressure mechanical encounter involving strict positioning, interrupt rotations, and specific environmental interactions to manage debuffs.

Strategy: The Melee Stack

1. Positioning & "Infection" Management
   • The 5m Rule: The fellowship should stay within 5m of the boss to prevent the Infection skill (Yellow Eye) from firing.
   • Infection Strategy:
     • Option A (Stack): Everyone stays in melee to avoid the eye entirely.
     • Option B (Bait): One player (typically a Lore-master) stays outside the 5m range to deliberately "bait" the eye, taking the damage away from the group.
2. Environmental Mechanics: The Permanent Flood

   The room floods in quadrants at specific morale thresholds. These floods are permanent and reduce the available fighting space as the battle progresses.

   • 80% Morale: 1st quadrant floods.
   • 60% Morale: 2nd quadrant floods.
   • 40% Morale: 3rd quadrant floods. The final 40% of the fight must be finished in the remaining 25% of the room.

3. The Cleansing Devices & Clinging Plague

   The Cleansing Devices (valves) are located in each quadrant. They are the only way to manage a lethal debuff:

   • Clinging Plague (Grey Bar Induction): Rádarríg casts this on the group, significantly reducing their Max Morale.
   • The Cure: The group must activate a Cleansing Device and stand in the immediate area to remove the debuff. Failure to do so usually results in the player being one-shot due to the reduced health pool.

4. Add Management (The "CC-Lock" Method)
   • Tiny Vermin: Spawn under players. Stack tightly so they spawn in one spot. Use AoE CC (Stuns/Dazes) to cancel their inductions (puddle drops). Kill them with passive AoE DPS.
   • Robust Vermin (Large): Priority Kill. Must interrupt all healing inductions.
   • Ferocious Vermin (Large): CC and Ignore. Keep it dazed/riddled. Do not kill it. As long as it is alive/CC'd, the next wave of large adds will not spawn.
5. Boss Skills & Reactives

Skill	Type	Effect	Strategy
Tail Whip	Induction	High AoE damage.	Interrupt immediately.
On Guard	Corruption	Reduces incoming damage to boss.	Strip all Corruptions asap.
Blighted Bite	Wound	Drops a damaging puddle only when cleansed.	Move to the edge of the safe zone before using a Wound Potion.
Vicious Slash	Debuff	Stacking incoming damage on Tank	It is reapplied instantly; healers must heal through it.

Alternative Strategy: The "No-Hit" Kite

It is possible to complete the encounter without the tank ever receiving the Vicious Slash wound and the boss gaining On Guard corruptions. This relies on Rádarríg's slow turn rate and movement speed.

1. The Pull
   • The Tank stands in Quadrant 2.
   • A second player (the "Bait") stays in a diagonal quadrant and pulls the boss.
   • The Tank immediately uses a Ranged Taunt to take aggro while the boss is still moving toward the Bait.
2. The Execution
   • The Tank begins kiting Rádarríg in a wide circle around the available "clean" space.
   • As long as the Tank stays ahead of the boss's melee range, Vicious Slash will never fire.

   Because the boss never hits the tank, he never gains the On Guard (Reduced Incoming Damage) corruptions.

3. The Trade-off
   • Melee DPS must be extremely careful; they must chase the boss and stay within the 5m "safe zone" while moving to avoid triggering Infection.

This strategy is highly effective for Ranged-heavy groups (Hunters/Minstrels) who can DPS while the tank circles the room.
