Attack pattern

The current data does not expose a simple fixed pattern. Read intent each turn and preserve an emergency block or potion line for the highest documented hit.

Preparation notes

Use the move table as a damage threshold, not a script that replaces reading the fight. Ascension, multiplayer scaling, powers, and patch changes can alter the exact line. For boss-specific planning, continue to the boss guide hub.
