Fight Mechanics
⬥ Poison
splats may appear, but they do not deal damage.
Attack Rotation
⬥ Normal Mode: Avaryss' Surge → auto attacks → Rain Death → auto attacks → Burn Phase → auto attacks → Repeat

Shared Health Pool
Mechanic:
⬥ Avaryss and Nymora share one health pool
⬥ When they are close together, AoE abilities can hit both twins and effectively damage the shared health pool twice
⬥ Hit caps do not apply to the Twin Furies' health pool, so some high-damage hits may deal more damage than the visible hitsplats suggest
Solution:
⬥ Use AoE abilities when both twins are close together e.g.,

⬥ High-damage combinations such as Chaos Roar
→ Overpower
will also go through the hit cap
Avaryss' Surge (Example)
Mechanic:
⬥ Avaryss jumps to a wall, then charges across the arena
⬥ This repeats 4 times
⬥ Avaryss always travels in cardinal directions, such as north to south or west to east
⬥ In Hard Mode, the dive can hit up to around 4,000 Melee damage, stun for 3 seconds, and disable overhead prayers
⬥ In Hard Mode, attacking Avaryss mid-jump can reflect 90% of the damage taken
Solution:
⬥ Move out of Avaryss' path after she jumps to a new wall
⬥ In Hard Mode, continually move to avoid being pushed and stunned
⬥ Avoid attacking Avaryss mid-jump in Hard Mode
Ceiling Collapse (Example)
Mechanic:
⬥ Nymora jumps to a random square and causes a ceiling collapse
⬥ In Hard Mode, Nymora yells "we will purge them all!" before the collapse
⬥ In Hard Mode, this deals rapid Ranged damage up to around 1,000 damage every 1.8 seconds
Solution:
⬥ Stand in the 3x3 area around Nymora to negate the mechanic
⬥ Use defensive abilities if needed while moving into position
Channeled Bomb (Examples) (Explosion)
Mechanic:
⬥ The twins move to the centre of the arena and channel an attack
⬥ If the channel finishes, it deals 4,500 damage in Normal Mode
⬥ In Hard Mode, this can deal up to around 8,000 damage
⬥ During this mechanic, the twins take 2x damage
⬥ You take typeless damage during the channel, which can be offset by Soul Split 
Solution:
⬥ Use AoE abilities while the twins are close together
⬥ Melee can use Cleave
, Hurricane
and Quake 
⬥ Necromancy can use Spectral Scythe
, Spectral Scythe II
and Spectral Scythe III 
⬥ Move or Surge
to the edge of the arena before the explosion or
⬥ Block the explosion with defensive abilities
Lava Bombs (HM Only)
Mechanic:
⬥ A lava bomb spawns alongside each main mechanic
⬥ Lava bombs bounce around the arena 5 times before disappearing
⬥ Green arrows show where the lava bomb will land
⬥ If you are within the 5x5 landing area, you take 3,000-4,000 hard typeless damage
⬥ After 2 bounces, a second lava bomb spawns
Solution:
⬥ Watch the green arrows and move away from the landing area
⬥ Keep moving while handling the main mechanic
⬥ Avoid pathing into Avaryss' jump path while dodging lava bombs
Blue Lava Bomb (HM Only)
Mechanic:
⬥ A blue lava bomb bounces around the arena 3 times
⬥ Green arrows show where the blue lava bomb will land
⬥ If avoided, it homes in on the player and deals 6,000-7,000 hard typeless damage
⬥ If the player takes the bomb, it also hits both twins for the same damage
Solution:
⬥ Intentionally take the blue lava bomb to damage both twins
⬥ Prepare defensives or healing before taking the hit
⬥ Avoid overlapping the blue bomb with other dangerous mechanics where possible
