Mechanics

	Bio II Scholar 26	Spell Job action
Effects	Inflicts Bio II for 30 seconds, dealing unaspected magic damage every 3 seconds Activates the global cooldown
Traits	Maim and Mend: Increases damage by 10% Corruption Mastery: Upgrades from Bio Maim and Mend II: Increases damage by 30% Corruption Mastery II: Upgrades to Biolysis
Interactions	Chain Stratagem: Increases critical hit chance against target by 5% for duration
Base damage over time formula: $Damage = \lfloor 40 * f(Magic Damage) \rfloor * f(Mind {DMG}) \rfloor * f(Spell Speed) \rfloor * f(Determination) \rfloor * Trait \rfloor +1$ Where trait can be 1.1 with Maim and Mend or 1.3 with Maim and Mend II.
Recast time formula: $Cast = \lfloor ( 100 - Haste ) * \lfloor ( 2 - f(Spell Speed) ) * 2500 \rfloor / 1000 \rfloor / 100$

Damage over time 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

Bio II is used to deal damage over time to the target. It should always be applied as soon as possible against a target to maximize its effects. Against weak enemies expected to die in less time than its duration it may be safely skipped.

As an instant cast spell that activates the global cooldown, Bio II can be used to weave abilities that are off the global cooldown in between spell casts, such as Whispering Dawn.

In order to maximize efficiency on Bio II, it is generally recommended to reapply it 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.

Behind the scenes

Final Fantasy XIV (Legacy)

The predecessor to the Bio II spell from the current version appeared at the launch of the original Final Fantasy XIV. Bio II (バイオII, Baio II?) was as an ability learned by Thaumaturges at rank 36. The spell dealt umbral-elemental damage over time and reduced the attack power of enemies within an area of effect. After patch 1.20, the Thaumaturge class could not longer use Bio II and no other class could use the ability.
