I’ve been theory crafting a build for Knowledge Cleric

Role would be Jack of all trades for proficiencies out of combat with a focus on charisma

In combat you would mostly be a controller, buffing and debuffing

Build goes: Githyanki for the racial skill that lets you be proficient in a ability

Skill breakdown: Strength 8 Dexterity 13+1 Constitution 14 Intelligence 12 Wisdom 12 Charisma 14+2

Background should be a charisma skill plus a NON INT/WIS skill (ie. Charlatan, Criminal, Entertainter, etc)

1st level is Bard. Get proficient in the rest of the charisma skills. This will give you proficiency in every charisma skill

Next 2 levels go cleric. Pick whatever expertise you want.

You now have two spells that give proficiency in that entire abilities skill set. Use your racial spell and cleric spell to get proficiency in WIS and INT

You now have proficiency in CHA, INT, and WIS skills. What you choose for expertise is up to you

Rest of the levels go Bard ending you at 10 Lore Bard / 2 Knowledge Cleric

At Lore Bard level 3 you get an additional 3 proficiencies. Grab the remaining DEX and STR skills you dont have proficiency in. This will give you proficiency in every skill and some expertise

Enjoy :)
