This article is about the skill level. For the ability, seeReason (ability).

Reason (Japanese:理学Science) is askill level inFire Emblem: Three Houses. Reason determines a unit's proficiency withblack magic anddark magic; it is a counterpart tofaith, the skill that determines proficiency withwhite magic.

Overview

Reason drives a unit's proficiency with black magic and with dark magic. Raising a unit's reason level allows them to learn newabilities and—rather thancombat arts—new spells in black or dark magic. Whether a unit learns black magic spells or dark magic spells through reason is determined per-unit: most learn only black spells;Edelgard andJeritza learn some black spells and some dark spells; andHubert,Lysithea, andHapi learn only dark spells. While both reason-based, black and dark magic are distinct weapon types and they do not both benefit from abilities likeBlack Tomefaire orDark Magic Avo +20, though they do both benefit from theReason series of abilities.

Common abilities learned through reason

Like other skills, every character learns certain abilities at a certain reason levels, learning a series of abilities that provide moderate benefits at lower levels and learning a -⁠faire skill at S+; unlike the skills relating to physical weapons—but like faith—S-level reason unlocks an ability that boostsrange rather thancritical rate. Because the abilities learned at S and S+ activate based on weapon types rather than skill levels, units that learn only black magic receive different abilities than those that learn some dark magic.
