Alvis/Gameplay (XC1)

Alvis is a guest party member in Xenoblade Chronicles. He appears in the battle where fights three Puera Telethia. His purpose is mainly to be a second person for Shulk to work with, so Shulk can use his positional arts and use for revival.

Notably, when Alvis encourages Shulk, Shulk is granted full talent gauge. This stops the fight from being rendered unwinnable if Shulk does not have Battle Soul earned or equipped, and thus otherwise cannot generate talent gauge if all remaining Telethia have Soul Read active. (Although if Shulk's gets too high in such a situation, it may be quite a while before he can be encouraged.)
