Enhanced Arcane Focus is an artificer infusion that's applied to a rod, staff, or wand, and adds +1 to spell attack rolls.
Alchemist artificers also get the Alchemical Savant feature, which lets them add their Intelligence modifier to healing and elemental damage rolls when they use alchemist's supplies as the focus.
On the surface, it seems like these features can't be combined: Enhanced Arcane Focus can't apply to the specific focus needed for Alchemical Savant. But artificers have a lot of versatility in the foci they use, and I know there are magic items out there that can improve this versatility further (like the Ruby of the War Mage).
Is there any way to use the attack bonus of Enhanced Arcane Focus (or any similar bonus to spell attack rolls, like a Wand of the War Mage) and the damage bonus of Alchemical Savant on the same spell?
