While not a given interaction, but merely as a possibility..

The artificer gains the Spell-Storing Item at level 11. You can imbue it with any 1st or 2nd level spell that takes one action. The item can be either a spell casting focus or a simple/martial weapon.

I've had artificers

  • Put cure wounds on guns (artificers get firearms) so you can shoot someone to health
  • Put Disguise Self on a club so they would "beat someone with the ugly stick."
  • Put Catapult on a javelin and use IT as the projectile
  • Continual Flame on a long sword to trick people into believing you had a Flame Tongue
  • And only by rule of cool; Rope Trick on a whip. Then literally "whip" the air to cast the spell
