The new Artificer class (from Unearthed Arcana) for 5e can infuse magic into weapons or shields, and use the infused item as a spell focus for material components. However, can you wave your focus for the somatic part of a spell as well?
Basically, I am curious whether an artificer can have a one-handed crossbow in one hand, and an infused shield in the other and still cast V, S, M spells.
