Accuracy is an important stat in FFXIV. Each fight has a minimum level of accuracy that you need to reach to be able to hit the boss 100% of the time. Missing an attack can make a big difference to your DPS, as it can mess up a whole combo, or make you miss a big hit.

There are different accuracy caps depending on where you are hitting the boss. These are calculated for the front (usually tanks, but can also be other roles, if you have to attack from the front at any point), flank (melee/physical ranged) and caster (caster ranged and healers).

Accuracy caps for all raids and extreme primals are found in the below tables. Note that these do not include the accuracy buffs tanks get from being in tank stance, and also that you can boost your accuracy by using the right kind of food.
