Summon Ice

Summon Ice is one of 's summoning arts in Xenoblade Chronicles. It summons an ice elemental that raises ether defence and can be discharged for decent chill damage.

Overview
Ice has a pretty slow cooldown (but only half that of earth), but since ether attacks cannot be dodged and thus will strike harder on average, this is a fair tradeoff. Summon Copy will be a good help for working around the cooldown if desired, though the cooldown upgrades rather quickly, so this is less of a concern later on.
