The Espers

And, why would FFXII 's Summons be useless? What do they do in battle? I can't find a good explanation, not even on GameFAQs.

When they are summoned (using a full mp bar), they replace two characters. The summoner is left with the summon. The summoner can heal the summon as the summon fights. The summon will attack the enemies until their timer runs out, or they die. If their timer runs out, they do an awesome finishing move. Apparently, the summons tend to be of little use against enemy bosses - hence my disappointment.

I went digging and discovered that some Espers won't do their finishing move until certain requirements are met.

For example:Ultima will only perform her finishing move(Perfect Ultima),unless her AND the summoner's HP is at critical levels.

Zodiac will only perform his special move(Last Eclipse),if the summoner is petrified.

They're are some others too.
