Byleth's Divine Pulse is arguably the best Action Ability in the game, as it freezes time for all surrounding enemies, including commanders, for as long as 20 seconds, allowing you and your party to simply pummel them with no resistance.
Byleth is obtained late in the game, making it tricky to raise your Support Level with them to A, but it's worth it to be able to give their powerful Action Ability to another character.
Be sure to raise your Support Level to A and watch the Support Conversations with Byleth before Chapter 15. After this point, you won't be able to watch Support Conversations anymore, making it impossible to obtain Byleth's Special Accessory without trying again on another playthrough.
