Find the Ancient Hammer at the west-Dirnado cove after the required radar upgrades, then use its Chamber of Arms pedestal. The radar guide separates Magi-tenna and Resonance Stone from the later merchant generator.
Bring Dark for the opening and Earth for the later forms, along with healing, ailment recovery and physical and magic protection.
Why is normal damage so low?
Tegmine has high defenses and a damage-reduction effect that drops while it is staggered. The opening also absorbs Water and Light. Repeating a large Light attack outside Stagger can therefore worsen the situation rather than solve the low damage.
Use an available Dark command to reduce the gauge, preserve resources for the break, then spend the strongest suitable damage actions during the actual opening. Its counters remain a reason to keep the party healthy while setting up.
Handle the later forms
- Confirm the transition and switch from Dark to Earth.
- Reestablish healing after counters rather than queue every ally into offense.
- Prepare for party-wide physical pressure, Paralysis and the control ailments from Stupefying Wind. A silenced or sleeping healer cannot execute the next planned spell.
- Keep death protection or revival available for the later Death threat. Inspect the warning before deciding whether to break, defend or recover.
The standard trial restores Thor’s Hammer. The level-75 ultimate trial awards its + version and requires a fresh preparation check. No fixed counter sequence or universal damage threshold is claimed here.
