Sanctissimus Shrine: Six Trials & the Paladin Duel

What opens the inner chamber?

Clear the six monster trials, then complete Rain and Lasswell’s Paladin duel. Read each stele before its corresponding battle. A single strong elemental loadout is not the solution to every inscription.

Enemy HP differs between the reviewed references, so this guide does not publish a universal threshold, recommended kill turn or difficulty-independent stat table.

The six monster trials in order

Trial	Effective approach	Failure condition to avoid
Archaeoaevis	Check its current weakness after Barrier Shift.	Repeating the opening element after the affinity changes.
Dad Bomb	Use Fire and prepare a finishing opening as HP falls.	Leaving the party exposed to Explode.
Test Rider	Earth or Light; respond to its calm and furious states.	Assuming its damage and defenses stay unchanged.
Yakhanati	Wind or Dark, switching between physical and magical categories.	Attacking into the currently ineffective category.
Two Arch Gargoyles	Wind or Light; bring both close enough for a coordinated finish.	Allowing the surviving partner to revive the first.
Dragon	Lightning, with recovery ready for its breath warning.	Spending the healer’s last safe action just before the burst.

How do you stop the Gargoyles returning?

Watch both HP bars. Prepare damage that can finish the pair within the same opening, rather than defeating one while the other remains far from death. Multi-target damage can help when it is actually available; selecting a single-target command does not spread the hit automatically.

For Yakhanati, the physical/magical distinction still matters even when both attacks use an effective element. Read its changed state instead of concluding that the listed element was wrong.

Prepare Rain for the final test

The Paladin duel uses Rain alone, so check his equipment, commands and recovery items. A healer or defensive Vision equipped on a different party member cannot participate for him.

Treat the duel as its own encounter and story transition. Do not rely on breaking a normal monster-sized Stagger gauge or importing the six-trial rotation. Continue through both parts of the confrontation and let the Paladin scenes finish.

Gelidus is a separate full-party battle

After the duel, the party returns for Gelidus. Recheck formation and Fire access before proceeding. The completed monster trials and Paladin title are the progression conditions; no extra shrine key is required. The Gronoa chapter guide covers the route into and out of the shrine.
