Use Master Seals for promotion

A base-class unit at level 10 or above can promote, usually choosing between two branches. Promotion resets the displayed level to 1; decide whether immediate stats or more base-class levels matter for the coming maps.
| Seal | Purpose | Key requirement |
|---|---|---|
| Master Seal | Promote a base class | Level 10 or above |
| Heart Seal | Personal alternative class | Unit’s available class set |
| Partner Seal | Borrow spouse’s class option | S support |
| Friendship Seal | Borrow friendship class option | A+ support; Corrin exception |
| Offspring Seal | Scale a late child recruit | Child’s supplied seal conditions |
Use Heart Seals for personal alternatives
Heart Seals access the unit’s own alternative class options. They do not reset level, so plan which class skills you need and when the unit can learn them.
Use support seals for borrowed options
Partner Seals use an S-support partner’s class options; Friendship Seals normally use an A+ partner. Corrin can use suitable A supports for Friendship Seals. Special classes and duplicate class sets create exceptions.
Check Offspring Seals before reclassing a child
Later child recruits may bring an Offspring Seal that adjusts them to campaign progress. Use it as intended before applying an unrelated class-change item, which can remove that opportunity.
| Check | Why | Decision |
|---|---|---|
| Target weapon ranks | A new class may start with weak proficiency | Keep usable equipment ready |
| Desired skill level | Skills unlock through class levels | Plan the learning route |
| Current level | Most seals retain it | Do not expect a free reset |
| Special class exception | Songstress and royal/beast classes differ | Read the offered class list |
| Offspring Seal present | Another seal can invalidate it | Use the intended child promotion first |
