Fighter: So uhhhhh... you gotta pretty neat weapon there.
Artificer: Thanks, designed "Ol Buzzy" myself!
Fighter: Mind if I give her a go?
Artificer: Sure, but you need any pointers?
Fighter: Naaaaaw, I can figure it out.
Artificer: *To the DM* CAN he figure it out?
DM: *To fighter* ...roll me a wisdom check.
Fighter: *Nat 1*
DM, Artificer, and Fighter in unison: Hoo boy.
