Inherit Skill is a gameplay feature in Fire Emblem Heroes.
Inherit Skill is an Advanced Growth option for the player to have their Heroes inherit skills from outside of the base skill set. Players sacrifice units with the skills they desire to pass on to the other units.
Players choose two heroes in their roster. Hero A will inherit the skills of Hero B. The player is allowed to choose up to four skills from Hero B to be transferred to Hero A. For the most part, skills are free to be transferred at the player's digression. Once the four skills have been chosen, Hero B is removed from the player's roster. Players are restricted from inheriting higher tier versions of skills until they have the required prerequisite skill tier(s) inherited or learned. For example a Hero must have Desperation 1 & 2 before they can inherit Desperation 3.
The Inheritance restrictions are as follows:
- All characters can only inherit weapons of their original weapon type.
