I think that’s a bit cheap for what basically amounts to an instant stun, especially when you can’t disarm them.
Really though, there isn’t really that many jobs that I can think of lack a specific item, aside from maybe the already mentioned engineers, and the bartender.
Honestly, my only idea is for everyone, in this case
Sonic Enhancement Device (SED): 14-16 TC: Grants a mask that looks similar to a security gas mask, but gray, and has more megaphones. Battery powered. Used a percentage of battery power to either :A Do a loud, AoE scream three tiles around the target, inflicting knockdown (not stun) for 2 seconds and deafening everyone hit for 7 seconds, or B: firing a sonic wave that travels 4 tiles, which will inflict knockback on the target, knockdown for 3 seconds, deafen them for 7 seconds, and stunning them if they hit a wall. AoE scream costs 30 percent of the battery, and the sonic wave will cost 25 percent power.
High price on this thing is to prevent people from just running this and E sword, since this is basically like an e bow, but less stealthy. This item isn’t disguised either. If hit with an EMP, it just loses some battery power.
If I think of any job specific items, I’ll post em.
