Summon Ice

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

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.
