Dolphin Blow is Tifa's first level 3 Limit in Final Fantasy VII. It is a physical attack on a random single target that strikes for 1.75 times Tifa's normal damage, in a combo with her other Limit Breaks. Dolphin Blow is a guaranteed critical hit if a "Yeah!" is landed on the slot reel, but will be skipped if the reel lands on "Miss". Using Dolphin Blow six times unlocks Meteor Strike.
Dolphin Blow is performed by an uppercut from Tifa, which is accompanied by a dolphin jumping in the air, synchronizing with her movements.
Dolphin Blow is obtained by Tifa killing 96 enemies after she has Waterkick. To do this quickly, the large forest in the Nibel Area past Mt. Nibel has six enemies in a single wave (Battery Caps), and approximately 4.4 enemies appear per encounter. Tifa can equip Magic Materia with All, or use Enemy Skill Materia abilities, such as Aqualung, to kill multiple enemies in one turn, although her Magic stat is lower than other characters'. If available, Slash-All is the fastest way for her to do this.
Dolphin Blow is used in a combo with all of Tifa's previously obtained Limit Breaks, meaning it is good to obtain it as soon as possible as it is a straight upgrade to her Limit Break.
Dolphin Blow is a physical attack on a random enemy, performed in a combo with Tifa's previous Limit Breaks (if they were not misses) and any obtained since, which deals 1.75 times Tifa's normal damage. If the player lands "Hit" on the reel, this is counted as a normal attack, but if the reel lands on a "Yeah!", the attack is a critical hit and its damage is further increased (approximately double). If the reel lands on "Miss" Dolphin Blow will be skipped in the combo.
Dolphin Blow's damage is based on Tifa's Strength stat and her currently equipped weapon. To maximize Tifa's damage output, a player can practice consistently landing a "Yeah!" with Dolphin Blow, though aiming for this increases the risk of landing a "Miss". "Hit"s with all attacks are sufficient to be on par with the damage output of other characters' level 3 Limit Breaks.
Dolphin Blow is used in a combo with Beat Rush, Somersault, Waterkick, and Meteodrive once it is first obtained. Landing a "Yeah!" on all five attacks gives Tifa the potential to deal more damage to a single target than other characters' level 3 Limit Breaks, and even on landing a "Hit" on all, this is on par if not slightly ahead of other characters. When used on a group of enemies, the attacks are randomly distributed among them, allowing her to wipe out waves of enemies with the combo. If one or more of the attacks miss, however, Tifa's damage output will be lower than other characters are capable of.
Dolphin Blow is a straight upgrade to Tifa's Limit Breaks, meaning there is no reason not to equip it once obtained.
