[RPG] Can a multiclass Warlock/Sorcerer use the Rod of the Pact Keeper as a spellcasting focus for both classes

Warlocks and Sorcerers share Charisma as their spellcasting ability and both can use an arcane focus. The Rod of the Pact Keeper is a focus for warlocks. Can a multiclass Warlock/Sorcerer use the Rod of the Pact Keeper as a focus for both spell casting classes but without the extra abilities the rod give the warlock?

Best Answer

Yes.

Let's make a little checklist:

  • Requires Attunement by a Warlock. You are a warlock, check.
  • It's an arcane focus. Both of your classes can use an arcane focus, check.

There's no reason you wouldn't be able to use as an arcane focus for both classes since you have the only two requirements of the item. As you said, your sorcerer spells can't benefit from the bonus but the special ability only requires you to hold the rod, use an action and have a spent warlock spell slot.
