Crystalians (Academy Crystal Cave)

The cave’s spear-and-staff pair combines repeated close-range thrusts with crystal spells.

Location and access

Academy Crystal Cave

Academy Crystal Cave

Starting Site of Grace: Academy Crystal Cave

Before you go

Bring two Stonesword Keys.

Stay at lake level on the western side of Raya Lucaria. Find Academy Crystal Cave in the cliff at the academy's base, use two Stonesword Keys at its imp statue and activate the grace inside. This is not Raya Lucaria Crystal Tunnel on the northeastern shore.
Follow the tunnel past the rats into the large chamber of glowing crystals. Deal with the nearer sorcerers before drawing the group farther left; the crystal outcrops give you cover from their spells.
Head north through the chamber, past the fireflies. The small cage room is a side pickup; continue toward the lantern-lit passage and open the wooden door.
The next room has a strong pointed-hat sorcerer near the doorway and another caster closer to the boss fog. Clear enough space to search without being caught between their spells.
Continue to the mist gate in the eastern corner and defeat the Crystalian spear and staff pair. Both must be defeated to receive Crystal Release.
The lift beyond the boss leads to another spell chest above the academy. Crystal Release is the direct boss reward, so it is already yours when the pair is defeated.

Notes

Defeat both Crystalians for Crystal Release. The lift beyond them leads to Terra Magica in a separate chest above the academy.
The cave entrance requires two Stonesword Keys. The Academy Glintstone Key is not the key used at this imp seal.
Use the statues to interrupt the staff wielder’s line of fire while you deal with the spear user.
Crack each enemy’s shell by breaking its stance. An upgraded Strike weapon or another stance-focused option helps you get through the protected opening.
The spear chain can last longer than the first few hops suggest. Wait for its finishing attack before trying a long punish.
Move clear of the staff user’s close crystal burst. Cover from the distant spells does not protect you if you stand beside the caster.
