Adding to what you mentioned
The Golden Glow (Charisma 2.0)
The Voice of Reason Audio Release
Actually just with the Blarney Stone is enough lol
All that we mentioned do the things you want.
But joining them harmoniously in one NFT with space for Captain to add freely the extras he wants could be great i can imagine.
And with whatever more you said you will add then thatd make it unique
Good luck!
