Attack Pattern

Three HP phases determine the normal sequence, while incoming physical and magical attacks select different counters.

Numbers count this boss’s own actions; combos are listed together. Battle-turn rules are labeled.

When	Action
HP at least 70%: first → second → third action	Choose from Bonebreaker (50%) or Rend (30%) or Stranglehold (20%) → choose from Bonebreaker (50%) or Rend (30%) or Stranglehold (20%) → Darkga (one party member).
First action below 70%	Reset to the first action of a six-action cycle.
HP 30–70%: first → second → third → fourth → fifth → sixth action	Choose from Bonebreaker (50%) or Rend (30%) or Stranglehold (20%) → Charge → Ruthless Rampage → choose from Bonebreaker (50%) or Rend (30%) or Stranglehold (20%) → 30% Death Claw / 70% Paralysis Fang → Meteor.
First action below 30%	Reset to the first action of a three-action cycle.
Below 30%: first → second → third action	Choose from Bonebreaker (50%) or Rend (30%) or Stranglehold (20%) → choose from Bonebreaker (50%) or Rend (30%) or Stranglehold (20%) → 30% Dark Apocrypha / 70% Darkga (the whole party).
When Devil Claw executes	Prefer a party member who has Reflect.

Pattern Changes

After being attacked, Beast of Ruin has a 30% chance to counter at HP 70% or above, or 50% below 70%. Use Flare after magic damage; otherwise use Devil Claw after physical damage.
After ten incoming magic actions while Beast of Ruin’s side has no Reflect, use Reflect on Beast of Ruin and start counting again. This takes priority over the ordinary counterattack.
After recovering from a stagger, immediately use Revenge Blast.
