Oho. In that case, before I roll again I wanna know if this is gunna work:

Kobold provokes an AoP from Orchid so she attacks, misses.

Masked guy provokes an AoP from Orchid, so she smacks him.

Because presumably this masked guy is going to move at least 5 ft, Orchid uses her Tunnel Fighter Reaction to smack him again.

Also regardless if she hits or not, the masked guy will be taking 4 thunder damage due to the Booming Blade effect.
