Pragmatic

Pragmatic is a skill introduced in Fire Emblem Fates. It is the Personal Skill of Leo.

Fire Emblem Fates
If Leo attacks or is attacked by an enemy whose HP is not full, he will deal three additional damage to his attacks and receive one less damage.

Trivia
Pragmatic is the inverse of Chivalry, Xander's personal skill, as Pragmatic receives its boost when Leo faces an enemy whose HP is not at maximum, while Chivalry does if Xander faces an enemy whose HP is at maximum.
