M Byleth War Master Build Advice (Maddening)

Hey everyone! I'm gearing up for a Maddening run with the Golden Deer route and planning to use Male Byleth.

I’ve seen a few posts and comments about a War Cleric → War Master build and it sounds like a fun and powerful path.

I’m looking for advice on how to optimize it: class progression recommendation, skills recommendation, equipment, etc.

Do you find this to be a strong build for M Byleth?

Thanks in advance 🙌
