Driver Skill

Driver Skills are unlockable upgrades for Drivers in Xenoblade Chronicles 2 and Torna ~ The Golden Country. They appear on a Driver's and can be unlocked using . Each one provides beneficial effects which increase the battle prowess of their Driver, with a variety of effects available such as increases or lengthening the duration of Driver Combo stages. Each Driver has two Affinity Charts worth of Driver Skills: one of which is available from the start of the game ("Overt Affinity"), and one of which is only available in ("Hidden Affinity").
==Overview==
Each Driver has 30 Driver Skills to unlock, 15 on each Affinity Chart. These are further divided into a grid of three rows and five columns, displayed as three rings with five skills on each.
* Skills on the innermost ring, level 1, have no prerequisites other than spending the necessary SP.
* Skills on the middle ring, level 2, cannot be bought until 2 skills of lower level have been unlocked.
* Skills on the outer ring, level 3, cannot be bought until 5 skills of lower level have been unlocked.
In addition, no skill can be unlocked without first unlocking all lower-level skills in the same column. These restrictions apply to Overt and Hidden charts independently.
Driver Skills are unlocked with . Each skill requires a certain amount of SP to unlock; higher-level skills and skills on the Hidden Affinity Chart tend to require more SP than lower-level skills and those on the Overt Affinity Chart.
Driver Skills can be divided into various categories, each represented by a different icon.
* The blue flexing icon tends to appear on skills that raise s.
* The orange sword icon tends to appear on skills that improve offenses.
* The yellow shield icon tends to appear on skills that improve defenses and healing.
* The green halo icon tends to appear on skills that have other supportive effects.
Many Driver Skills appear on the Affinity Charts of multiple Drivers (albeit with different names). In particular, if a skill is on the Overt Affinity Chart of one Driver but not another, it will typically be on the latter Driver's Hidden Affinity Chart.
==Strategy==
The most important Driver Skill for each Driver to obtain by far is (or the equivalent on other Drivers), which allows one to cancel a Driver Art into another Driver Art, drastically improving both damage output and buildup. This should ideally be obtained as quickly as possible - how quickly this is depends on the Driver, but in most cases it will be obtained around the early-middlegame at the earliest.
Each Driver has three Overt skills of the form "allows use of the Driver Art assigned to (this button) at the start of battle". This can be nice, but as it is naturally a once-per-battle benefit (and only saves a few seconds) it is not necessary to prioritise over other skills. As the relevant skill for the X button will generally be unlocked first, setting Driver Combo-inflicting Arts to this button may be helpful to increase the chance of an early Driver Combo (and thus potential Fusion Combo) setting the flow of battle. Aside from these skills, the ones with green icons are all generally very useful and it is wise to prioritise them after obtaining Arts Chain.
Other skills vary in utility, but there are no general rules as to in what order they should be obtained; the best are often dependent upon the player's chosen setup.
