Tri-disaster is a Summoner ability from Final Fantasy XIV that deals single-target damage while inflicting both Bio and Miasma.

Mechanics

PvE version Tri-disaster Summoner 56 Ability Job action Effects Deals unaspected magic damage Inflicts Bio II and Miasma for 30 seconds, dealing additional unaspected magic damage every 3 seconds Traits Maim and Mend II: Increases damage by 30% Corruption Mastery II: Upgrades effects to Bio III and Miasma III Interactions Fester: Deals increased damage to targets suffering from Bio and Miasma effects Bane: Spreads Bio and Miasma effects to nearby enemies at 60% reduced potency Devotion: Increases damage dealt by 5% Dreadwyrm Trance: Resets recast timer Firebird Trance: Resets recast timer Base direct damage formula: $Damage = \lfloor 150 * f(Intelligence_{DMG}) * f(Determination) \rfloor * f(Magic Damage) \rfloor * 1.3 \rfloor$ Base damage over time formula: $Damage = \lfloor Potency * f(Magic Damage) \rfloor * f(Intelligence_{DMG}) \rfloor * f(Spell Speed) \rfloor * f(Determination) \rfloor * 1.3 \rfloor +1$ Where Potency can be 30 for Bio II, 20 for Miasma, or 45 for Bio III and Miasma III. PvP version Tri-disaster Summoner 30 Ability Job action Effects Deals unaspected magic damage Inflicts Bio III for 18 seconds, dealing additional unaspected magic damage every 3 seconds Grants 1 Aetherflow Gauge unit, represented on the job gauge and by the Aetherflow status Interactions Fester: Deals increased damage to targets suffering from Bio III and requires Aetherflow Gauge to use Bane: Spreads Bio III to nearby enemies and requires Aetherflow Gauge to use Painflare: Requires Aetherflow Gauge to use Dreadwyrm Trance: Resets recast timer and requires Aetherflow Gauge to use Firebird Trance: Resets recast timer and requires Aetherflow Gauge to use Phantom Dart: Increases target's damage taken by 20%

Damage over time (DoT) effects deal damage every server tick, or 3 seconds, independent of the effect's duration. This means that the effect may deal damage anywhere between 0 and 3 seconds after it is applied, and in 3 second intervals afterwards.

Use

Tri-disaster deals instant damage to a single target and inflicts the user's strongest Bio and Miasma DoT effects on the target. Having both statuses in a single ability saves the Summoner from spending two global cooldowns (GCD) to inflict them with the usual Bio or Miasma spells, improving overall DPS. When accounting for the total damage dealt by the two DoT effects and Tri-disaster's own base potency, it is the most powerful single-target action in the Summoner's arsenal.

Tri-disaster's 50s recast is longer than the 30s duration of the statuses, forcing the Summoner too occasionally use the base spells to reapply the statuses between Tri-disasters. However, both Dreadwyrm Trance and Firebird Trance, learned at levels 58 and 72 respectively, reset the recast timer of Tri-disaster when used, further reducing the Summoner's reliance on the base spells.

Statuses inflicted by Tri-disaster benefit from all the same synergies as though they were inflicted by the regular spells, increasing the damage dealt by Fester and potentially being spread to multiple targets by Bane.

Tri-disaster is an instant cast ability that is off the global cooldown (oGCD). This allows players to weave it between global cooldowns after using instant cast spells such as Egi Assault II, and is best saved for these situations in order to maximize DPS. It is even possible to double weave Tri-disaster with the aforementioned Fester or Bane within a single GCD.

In order to maximize efficiency on DoT effects, it is generally recommended to reapply them with under 3 three seconds remaining, as the final tick of damage from the effect can occur anywhere in that window. This may result in the loss of a tick, but waiting for the effect to drop off before reapplying can result in the loss of two or more ticks and greater DPS loss.

PvP

Tri-disaster only inflicts Bio III in PvP due to the absence of Miasma spells. In exchange, it now also fills the Summoner's Aetherflow Gauge. With Energy Drain being a spell in PvP and the only other Aetherflow generator, this allows Tri-disaster to still save the Summoner the use of two GCDs.

Much like the PvE version, Tri-disaster has a long cooldown, necessitating the occasional use of the regular Bio III spell. Aetherflow is also only generated one at a time, so Tri-disaster can't be relied on as a Aetherflow generator, instead using the GCD Energy Drain to fill most of their gauge.

In PvP, Aetherflow is required to use Bane, Dreadwyrm Trance, and Firebird Trance, in addition to Fester and Painflare. Fester, Bane, and the Trances all retain their usual synergies with Tri-disaster.

Patch history

Version	Changes
Heavensward	Added with a 60s recast. Inflicted Bio, Bio II, and Miasma with 18s, 30s, and 24s durations respectively. Bio and Bio II were distinct statuses at the time rather than Bio II being the upgraded form of Bio.
Stormblood	Bio and Bio II statuses made mutually exclusive as Bio II now replaced Bio. Due to level restrictions, Tri-disaster can no longer inflict Bio. Level 66 trait Corruption Mastery II added, upgrading Bio II to Bio III and Miasma to Miasma III. Tri-disaster inflicts the strongest versions of Bio and Miasma available, and thus inflicts Bio III and Miasma III when this trait is active. Tri-disaster now inflicted Ruination in addition to Bio and Miasma. Ruination increased potency of Ruin spells against affliced enemy by 20. All Bio and Miasma effects had 30s duration while Ruination had only a 15s duration. Dreadwyrm Trance now resets Tri-disasters recast. No longer available in PvP.
Shadowbringers	Recast time reduced to 50s. Ruination now also increased Outburst potency. Ruination no longer increased potency of Ruin spells used by Scholars. Level 72 trait Enhanced Bane added, allowing Bane to spread Ruination to nearby enemies. Level 76 trait Enhanced Tri-disaster added, increasing Ruination's duration to 30s. Firebird Trance added, also resetting Tri-disaster's recast like Dreadwyrm Trance.
Patch 5.05	Delay before statuses are applied reduced.
Patch 5.1	No longer inflicts Ruination. Now dealt unaspected damage with 300 potency. New PvP exclusive version added. See below for its patch history.
Patch 5.3	Potency reduced to 150.
