Swap is a mobility assist skill, only one of two capable of moving both the user and target of the skill. Its uses are limited, but powerful. Swap effectively gives an ally a potential extra space of movement. It’s most common use is defensively: An ally who is in danger can be swapped out by the user of the skill, putting themselves in harm’s way. In this way, it’s similar to Pivot, but does not require an empty space in front of the target for the skill to activate. Swap is one of the easiest Assist skills to use, and one of the most versatile: It can be used to grant the user or ally an extra movement space, or take them out of harm's way.
Swap is best used by units with high defense, to take the place of weaker units on the frontline. As a space isn’t required in front of the target (unlike Pivot) this skill benefits offensive units who attack from melee range. Brave Weapon and Blow Skill users are excellent examples of units who benefit from receiving a Swap. They can launch their attack, and avoid taking damage the following round. Good users of Swap are those who can easily handle being attacked. Units with skills like Vantage and Quick Riposte can take advantage of Swap. The extra movement space is well appreciated by Armored units. Wings of Mercy and Swap form a deadly combination: It lets a unit teleport and take the place of a wounded ally.
The main disadvantage of Swap is that is places an ally into danger. However, if used by the right unit, this can be one of its best traits. Swap is poor against defending from ranged damage as the target is only moved a single space away from their original location, still able to be attacked by an enemy ranged unit. Swap is a skill with nearly no downsides save for opportunity cost, and is one of the most versatile and useful Assist skills.
