Ice Prison

Ice prison is an icebending ability that allows the user to encase enemies in a snare of ice. This prevents them from moving or attacking, but they can still use bending.

Unlocking this ability requires a tier II icebending scroll or a tier I universal scroll.

Level II
Increased duration of the ice prison.

This ability upgrade requires a tier I scroll to unlock.

Level III
The prisoner takes damage when the ice prison shatters.

This ability upgrade requires a tier II scroll to unlock.

Level IV
As with all other abilities, there are two choices for Ice Prison's level IV upgrade.

Frostbite: Deal constant damage while enemies are trapped in the ice prison.

Frostbite allows the ice prison to constantly deal damage to the prisoner. This ability upgrade is recommended for icebenders who would like to use this ability as an offensive one.

This upgrade requires a tier III scroll to unlock.

Glacier Ice: The ice cannot be melted by the sun or firebending.

Glacier Ice grants the ice prison immunity to the flames of both the sun and firebending. This ability is recommended for icebenders who want to either extend the duration of the ice prison or who want immunity against firebending.

This upgrade requires a tier III scroll to unlock

Mechanics
Unless upgraded to prevent this, icebending attacks will all melt against firebending.
