Im thinking of playing a artificer /armorer and arcane trickster rogue

 hi guys and gals,

  I've been looking into the artificer armorer and arcane trickster.... as a multiclass i was thinking of going 11in artificer and 9 in rogue following the arcane trickster tree my thoughts on the build.

Reasons for the split build Infiltrator armor Dampening field. Expanded field of spells. Magic tinkering items Use to cause a distraction for rogue skills like mage hand to move a lighted stone around to prompt a sneak attack on a distracted enemy. also adding addition attack using the artificer tree. the eventual scimitar of speed. adding a 3rd. Infusions to boost the stats to the armor. higher survivability with the stronger armor, extra magic item attunement, the ability to make a spell storing item at (lvl 11 arti) use of a friend or a homunculus to use magical ambush at lvl 9 trickster. uncanny dodge from rogue. the movement speed increase from the infiltrator armor, it just stacks really nicely with the arcane trickster spells and artificer infusions and spell list not to mention the stat increases per each class should balance out nicely as it progresses

                                                                                                                                                                                     what do you think any suggestions or critiques?

If its a level 20 oneshot, i suppose .  Artificer is good for a 3 level dip for armorer so you can run around in plate. But if youre playing a rogue, youll max your dex and could wear studded leather. But then it will be tough to also max your int for artificer stuff.,

I suppose you could max your int and use your lightning launcher for sneak attack since its a simple ranges weapon. But then youre a rogue who cant pick pockets or locks?

The build could be a bit MAD.
