The two-move loop
Unexpected Zooming starts at a distance and suddenly crosses the party for 4 damage. Statue Smash rises over its target and slams twice for 2 each. After the first slam, stay ready for the second preparation and impact.
Use the nearby recovery point
The castle encounter starts in the left corridor after the spiral stairs, near a green healing pad and spawn point. Recover before triggering the cutscene. The base statue has 14 HP, 1 DEF and Mobile.
Multiple-statue encounters
The enemy also appears in the Pit and as a Blackrock King summon. Removing one from a group reduces the number of party-wide rushes to guard; the original one-statue loop does not describe a full multi-enemy turn.
