Repeating Crossbow + True Strike + Arcane Firearm?

Quote from Udaydar >>

Also, if you doing like me, gonna choose lvl 4 sharpshooter feat then won't have to worry about range as much since will be able to do 90ft without disadvantage.  Figure theme wise it makes sense for artillerist plus cantrip truestrike works with sharpshooter feat.

You could also choose Spell Sniper instead of Sharpshooter. It won't affect the range of True Strike (but will affect the range of many other spells), and still lets you cast at melee range and ignore partial cover...and, importantly, can be used for +1 INT.

Fair! Vicious Crossbow is a good option if you don’t want to (or can’t) use magic.
