Thankfully the high-level artificer abilities aren't that amazing, so we don't lose out on much. Thankfully we can combine the archetypes in ways to alleviate most of this but ultimately in any multiclass build we're sacrificing the late level capstone features and specializations of a single-class character for more options and utility. This also means that you'll need to meet the artificer multiclass requirements and the rogue multiclass requirements. We'll also be pretty low on hit points compared to other martial characters since even single class rogues aren't all that beefy. Artificer multi-classes have a similar issue as a partial spellcaster, and any levels not taken as artificer levels will hurt the already wimpy artificer spell progression and spellcasting abilities. A rogue's sneak attack is determined by their rogue levels not their character levels, this means we're taking a big attack damage hit with any levels not taken in rogue.

Multi-classing an artificer and rogue isn't the smoothest combination. Want endless dice? Check out our RPG Dice Subscription! You get to be Q and James Bond all in one! The slow level progression on sneak attack hurts, but we can offset it. You end up with a bit more than a sneaky artificer or a rogue with additional spellcasting options and when multiclassed right you'll end up as a rogue flush with all sorts of utility spells with tons of useful gadgets for their stealth missions and a robot pal to provide sneak attacks for combat.

Instead, we're going to focus more on the features of rogues augmented and enhanced by the utility features and additional damage options of the artificer. Your first instinct may be to take the artillerist for the eldritch cannon, but no matter how I tried the math artificer rogue multiclassing always left me with simply less damage when using the arcane cannon. The rogue dnd class is one of the best offensive options in the game and is the archetypal sneaky character, but wouldn't it be nice if they had some gadgets? In an odd way both classes make use of and gain bonuses towards their thieves' tools and while they don't seem like they'd mesh as multiclass options it actually works. The artificer class has a lot of fun combat buffs and support options but have serious combat limitations, even the artillerist is just halfway decent at it.
