Ways to get Caster Levels without multiclassing

[KunoichiSong]

Are there any? I want to grab Share Spells Teamwork feat with a friend, but he wants to go full Samurai...

Are there any feats that would allow this?

After reading the feat Share Spells, I don't think your friend needs the feat Share Spells, they seem to just need the teamwork feat Bonded Mind to gain the benefit of the share spell feat (although it's a teamwork feat).
