Agility

Agility (すばやさ) determines a character's priority in turns, utilizing a Gaussian Curve with simple calculations. In the NES versions of the first four games, as well as all versions of Dragon Quest III, agility also contributes to the character's innate defence. If a character has no armour or other defensive gear equipped in these titles, then their defence will be half (50%) of their agility. Any character can consume a seed of agility to increase this attribute.

Dragon Quest

Turn order is strictly dependent on the enemy in the NES version, with a 100%, 50%, 37.5%, and 25% chance for them to strike first.

Dragon Quest II: Luminaries of the Legendary Line

(Agility/2) + N, with N being 0~255. NES version only.

Dragon Quest III: The Seeds of Salvation

(Agility + 20) * (N/256), with N being a random number between 0~255.

Dragon Quest III HD-2D Remake

Turn order is calculated as ((Agility stat + buffs) + 20) * (N/100), with N being 50~100.

Dragon Quest IV: Chapters of the Chosen

Currently unknown.

Dragon Quest V: Hand of the Heavenly Bride

SNES version is calculated as Agility * (75 + N * 26/256)/100, with N being 0~255.

Dragon Quest VI: Realms of Revelation

All versions are calculated as (Agility + 20) * (N/100), with N being 50~100.

Dragon Quest VII: Fragments of the Forgotten Past

The original and remake use the same algorithm as found in VI.

Dragon Quest VIII: Journey of the Cursed King

Turn order calculation is slightly tweaked, with enemy agility directly involved in the algorithm instead of just being measured against. The chance for a character to act is (ally Agility)/(enemy Agility) * 50, with the result being converted to a percentage.

Dragon Quest IX: Sentinels of the Starry Skies

Turn order is calculated the same way as in VIII.

Dragon Quest X

The tenth game operates in real time, so players can act as quickly as they can input commands. Agility reduces the interval between actions, which is the period of time between when an action is executed and when the command window appears again to input another command.

Dragon Quest XI: Echoes of an Elusive Age

Currently unknown.
