"Frey!" Levin Cloud stated as only him, the wood elves, and the injured ones behind him are not frozen.
[All beings that are Frozen cannot be killed while they are unable to move. Damaging frozen beings will thaw them or being exposed to extreme heat will also release them.]
Levin Cloud saw the notification and he could see in their party tab that Frey and Peridot are alive. The only reason they cannot actively move is due to the fact that they are frozen in place. Peridot is even frozen in her dragon form which is testament to how powerful the freezing power of the cold.
"Freeze the Forest Guardian so we could be on our way. Kill the remaining ones." The Frost Elf Leader stated as he once again released a burst of cold energy from his sword.
