Glacial Freeze (also known as Glacier in the SNES/PS version) is a Double Tech used by Marle and Frog in Chrono Trigger. It's learned once both characters learn Ice II and Water II respectively. Deals massive Water damage to a single enemy.
Description[]
When used, Marle and Frog combine their magic, and rise off-screen, after which a massive waterfall and three icebergs rain down on top of the enemy, chilling and damaging the enemy in the process.
