Blue Fire Domain.
Cold Haze.
When Eliza succumbed to Eren's spell, she sensed her body heat siphoning away, compelling her bodily functions to decelerate.
This happened despite her attempt to shield herself from the blue flames by enveloping her in the Enderflames.
The blue flames didn't scorch Eliza's skin, but an unwarranted hibernation-like effect seized her. Her body temperature would have plummeted dangerously against Eren if not for her Enderflames, guarding her from frost-like damage.
Encountering a fire-element Ranker using a uniquely employed Way of Fire was a first for Eliza. Opting for a defensive stance, she curtailed her offensive moves, precisely timing and matching Eren's attacks. Yet, being on the defensive meant enduring accumulating injuries with no immediate prospect of reciprocating damage.
