Leviathan (Final Fantasy V)

Leviathan is a level 5 summon in Final Fantasy V met in the main story, but is optional to obtain. It is a water-elemental summon who uses Tsunami, a powerful attack dealing heavy water damage to all enemies. Leviathan is one of the common summoned monsters found in Final Fantasy.
Leviathan can be used via Summon and Call once obtained, and also via Magic Lamp. With the latter two, the summoner uses no MP.
==Obtained==
Leviathan guards Istory Falls, protecting the tablet that lies there. The player does not need to fight him when they first arrive, and can return later to confront him, if needed.
==Stats==
Ability	MP cost	Power	Effect
 	39 	195 	Water-elemental damage to all enemies.
Tsunami's damage is calculated as follows:
:Attack = 195 + (0..(195/8))
:M = (Level \times Magic Power)/256 + 4
:Defense = Magic~Defense
:Damage = (Attack - Defense) \times M
As a summon, there is no split damage property, and Tsunami is unaffected by reflect.
If the target absorbs water, it is healed instead of damaged; if it is immune to water, the attack misses. If the target resists water, the Attack modifier in the formula is halved, but if it is weak to water, the modifier is doubled and the attack ignores the target's Magic Defense.
Several pieces of equipment increase the power of elemental attacks by 50%, but none of them affect water. The only way to boost water damage is via the Mix Elemental Power that empowers all elements.
==Use==
Leviathan performs the attack Tsunami when summoned, dealing heavy water-elemental damage to all enemies. The damage is almost twice that of Titan and a little stronger than Syldra, but is less than Bahamut. Leviathan has a somewhat high MP cost, but one that is less prohibitively high than Bahamut.
Leviathan is one of the strongest spells available. Aside from Meteor and Bahamut, it is the best spell to cast to hit all enemies, and can be used effectively with Dualcast. Though Bahamut is stronger, Leviathan can still be a better choice when being more conservative with MP, or when targeting an elemental weakness.
