Crimson Longinus
Legend
Oh, so now you're saying that you can't cast spells with one hand at all?We aren't talking about opening/closing a door or something. Do you have everyone using homebrew ioun stone style spellcasting focus items that float or come with their own hand so they don't fall when the PC drops it to put their hand back on the weapon? a player can't interact with the focus and stow the focus and interact with their weapon as their one free object interaction.
And it was about components, not the focus, but given that the focus can be just some trinket that hangs on their belt or neck, they certainly could use it with one interaction.
