Tri-Disaster(トライディザスター, Torai Dizasutā?), also known as Tri-Dazer or Tetra-Disaster, is a recurring attack in the Final Fantasy series. It usually deals multi-elemental damage, specifically Fire, Ice and Lightning.
Tri-disaster appeared in Final Fantasy XIV from version 2.0 to 2.55, as a Summoner ability available after completing the "Shadowing the Summoner" Summoner story quest. The ability deals small non-elemental damage and causes a 20 second bind to the target and nearby enemies.
Since version 3.0 (Final Fantasy XIV: Heavensward), the old Tri-Disaster was renamed to Tri-Bind (トライバインド, Torai Baindo?) and a new Tri-Disaster skill was given to Summoners after completing the level 56 job quest. When used, the ability will instantly inflict the Bio, Bio II, and Miasma damage over time effects to an enemy. This change was done due to Naoki Yoshida believing that the original ability did not live up to skill's name.
