Khuzu's Thunder

Effect

Sweeps a damaging lightning beam across 180 degrees, freezes enemies it hits, and fires every 2.5 seconds.

Rite and discovery

The Last Ward route requires the Stay, Strong, Soul Family, its active Synergy, and live Altar Seals on all three member Spells: Death Trail, Lamb Lamp, Witch Shield.

This is a starter candidate for Last Ward.

Access note

Completing Chapter I on Mortal permanently unlocks Moonwake Dancer and Stay, Strong, Soul. Eligible test accounts may have temporary access before that clear; see Characters and Families.

Advanced Spell rules

Khuzu’s Thunder is not one of the three Family member Spells. It has no ordinary level-up path or Altar form and carries no seal; the active Family may still apply its authored modifier to this eligible Advanced Spell. Choosing it leaves all three source Spells, their seals, and the active Synergy in place. A build with an Advanced Spell cannot resolve another Rite.

See Rites and routes for the three-seal rule and boon behavior.
