Having spoken her final words, the ice pillars beneath Ivita and the Hearsthone Witch shattered with a roar, and both of them dropped along with the scattering ice fragments.
But in that instant, Ivita and the Hearthstone Witch transformed into a falcon and a vulture respectively.
"A Rule-series complete transformation skill?" The Lich's soul shook her head, coldly watching from atop an ice pillar as the falcon that Ivita had transformed into dashed with lightning speed through the falling shards of ice. She waved her hand, and numerous grey ice thorns flew out from the folds of her sleeve.
This was a Witch Marquis level complexity magic spell - Grey ice magic.
A blend of necromancy and ice magic, anyone struck by the grey ice thorn would have their life instantly frozen, leading to their immediate death.
Even a fully-fledged Knight would instantly die under this spell.
Indeed, her use of this spell in spirit form would certainly diminish its power.
