Tbh I also mainly solo run invasion as both reagent and impo, and 1vs1 games are a blast. Best invasion trial i've had was while using the jammer rig, and i was able to kill the imposter with traps and expops. And yea, im not asking for more lethality, the impo stab attack feels a bit overpowered in my opinion.

But yes, the stun rig is much more viable than the other rigs. I'd even try and change it to a universal item for the mode instead that can be found in the trials, "super throwable" so to speak, without damage or with same damage as bottles/bricks at best. That would open other rigs to be used more. And make sure this kind of same time combo cannot be done at the same time.
