Yesterday Jedi in my party attacked a minion group of 5 imperial trooper

he rolled enough advantage to activate a sunder multilple times, so he wondered if could sunder minion's weapons... and if that would results in all of them losing the weapon, or just one...

How many Advantages did he have and how many minions?

Keep in mind that you have to activate Sunder like four times on a single weapon in order to actually sunder it. Each activation causes the weapon to be damaged by only one level, and there’s four levels to the damage state of a weapon.

With five minions in the group, and four levels of damage per weapon, that would be twenty activations you have to go through, before you can sunder all the weapons of all the minions.

If you did activate Sunder four times, you could do that all against the same weapon, which would then render the minion group as effectively one individual lower in number as far as weapons are concerned.

This is just another slice of the minions vs. individuals argument.

There's minor, moderate, and major damage, with the difficulty of using a weapon increasing with each level of damage.

That's three advantage to completely mess up a weapon.

Like what bradknowles said, you would need a lot of advantage to sunder each and every weapon.

If there minions, as GM I would happily let him use that advantage to activate critical hits (if he had enough advantage), and to have those critical hits be full-blown sunders on some of the Imperials, in response to which some of those minions go a-runnin' scared.

Ok thanks

he had 3 advantage (AFAIR... enough to completely disabilitate ONE single weapon)...

so long he could destroy a single minion's weapon and not for everyone

I would let him sunder all the weapons a single step with each advantage, so with those three advantage the entire group have unusable weapons, their minions! They are a single target and are supposed to be the stuff PC's knock around to make them feel powerful. If you now need reinforcements for your devious plans just flip a DP the next chance you have...

Edit: I mean if you disorient a minion group they all cop it, if you stagger them same thing, they are supposed to be easy to use, easy to kill. not some finely tuned micro-maneged perfect killing machine.

I agree they are just a quick-to-kill enemy (and also it's pointed more to showoff: killing 20 stormtrooper (minion) is funnier than killing 4 ones (rival)).

However, it's the opposite of granade: with granade, every single minion get damage (if blast trigger) and that damage also goes into same wound pool.

I agree that disorient, stagger and other impairing effect will apply to the entire group; just wondering if sunder will do same thing...

applying sunder to a minion group is not making a fight more easy, it's just getting them more boring...

I would make it apply to the whole group. Less keeping track of what minions still had guns. Narratively each "step" of damage might be a minion losing a gun or something.

It'd depend on what the intent of the Jedi was. If they were trying to disable the minions without killing them, then I'd apply the damage to them, allowing for crits as usual, and "narrate" that the player sundered the weapons of as many minions as they would have killed had they been focusing on the minions instead of their weapons. This gives them a non-lethal method of dealing with average guys without worrying too much about the details of the sunder rules.

Rivals, are, of course, another story entirely.
