Heart Seal

Parallel Seal
The Parallel Seal is a reclassing item introduced in Fire Emblem: Fates and replaces the Second Seal from Fire Emblem: Awakening.

Uses
The Parallel Seal allows a unit to reclass into an alternate class. However, unlike the Second Seal, it does not reset the unit's level. The unit will then learn the skills it missed in the new class line after each consecutive Level Up. For example, if a Level 12 Mercenary reclassed into a Ninja, it would learn Locktouch at Level 13 and Snake Venom at Level 14.
