I want to create a celestial warlock and I want to have Shillelagh as one of my Pact of the Tome cantrips.
I also wanted wooden staff as an arcane focus so I can use melee and free up my other hand.
Are the Pact of the Tome cantrips treated as warlock cantrips, which would let me use my arcane focus, or would I need a separate Druidic focus?
For example, to cast Shillelagh you normally need to have mistletoe and a shamrock leaf. Would my warlock focus let me forego the need for the material components, or would I need a druidic focus too?
