Since I can't think of more, I might as well take some from the web:

PHOENIX
Rebirth Flame: Normal Version.
Eiko summons Phoenix to inflict a small to moderate amount of fire-elemental damage on all enemies, while all KO'd allies are brought back to life with (30 + their Spirit stat)% of their Max HP recovered. The amount of damage and HP recovered is weaker if the shortened version of the summon is activated.

Rebirth Flame: Auto Version.
This summon ability is activated when all characters are KO'd. Eiko consumes no MP to have a chance at reviving all characters with (30 + their Spirit stat)% Max HP recovered, however no damage is done to the enemy. The chance of this happening is equal to the number of Phoenix Pinions in your inventory ÷ 256.

ODIN
When Odin is summoned either one of two things will happen. Note though that the following attacks will be weaker if a shortened animation occurs.
1) He will causes instant death to each enemy with a chance of (#Ores in stock ÷ 2)%. If that fails, Odin will miss.

2) If Garnet is equipped with the Odin's Sword ability, then Odin will inflict non-elemental damage on all enemies that survived his instant death attack. (Spell power = 142 - #Ores in stock).

Eidolon: Trance Version (0 MP)
After being summoned, a shorter animation will activate at intervals to cause non-elemental damage on all enemies. This continues until Garnet uses another Eidolon. (Spell power: 49)

If I'm happen to be right, you just take the turn over again, I'm not feeling very good these day.
