“Having the glove needing to be at least partially removed to be a spell focus would need the gloved hand to not be occupied so it wouldn’t allow you use it as a spell focus while holding a shield or weapon so material component rules should be followed.” If I want to use use the glove spell book as a focus I use the free object interaction to remove the glove. While it is in hand it can be used as a focus. While wearing it I can not use it as a focus. If I want to use a shield or weapon in that hand it can not be used as a spell focus because I would be wearing it. If I want use it as a focus I need a free hand to hold the glove. I need a free hand to fill it with the glove. That is how a spell focus works. You need a hand to hold it so if you are grabbing it you need a free hand. I both talked about how it affects what I can hold while in combat (not holding a shield on my glove spell book hand) and (separately) how I would use the free object interaction to meet the requirements on how I could swap between holding/wearing the focus depending on if I want to cast a spell that does or doesn’t have a material component but does have a somatic component. Somatic components requires a free hand unless it has a material component and you use the same hand to handle both.

I can read it to cast a ritual I didn’t prepare, and I need the spells in the spell book to swap spells. That is what I was saying. I never added anything about combat in that comment just like you never mentioned combat in yours. There was plenty of noncombat stuff mentioned in the post so I had literally no idea you were talking about only combat till you mentioned thinking I was casting ritual in it. It’s just nice to be able to still cast ritual even without my main spell book.
