Attacks Affected. You have
Disadvantage on attack rolls against any target
other than the grappler.
So you are giving disadvantage to hit the grappler. Which would of been the target.
Yeah something he could have done easier with a net and just as easily by kocking the guy prone in addition to grappling him.
Plus giving everyone advantage, and helping dex saves too.
Again something the guy grappling could have done easier by himself with a net.
If you want to get away, use Withdrawal.
Do you mean disengage? and give up your sneak attack?
But even without moving, attacking you with disadvantage is better than attacking the grappler with a normal attack.
No it is worse, and like I said it probably won't be with disadvantage. Even if you don't provoke., they use their first attack to knock you prone ... and then attack you without disadvantage .... or knock the grapppler prone and attack him without disadvantage.
You are using an attack to cause with a failed save and then a bonus action with a check to do what could be acoomplished easier with just an attack and a failed save.
It's unique that it's a bonus action, automatically works, and takes a action to remove, yes. You can still make your sneak attack with advantage.
First it is not just a bonus action. It is a bonus action PLUS either an action or an attack to set the conditions to attempt it.
You can't do this unless/until the target is grappled or incapacitated and that means you or an ally is going to have to take an action or an attack to do this first.
Second, it does not automatically work. Getting someone grappled or incapacitated is not automatic and will require a failed save. Then you need to make a check which can be automatic but is not going to be automatic for many/most PCs. There is a minority of Thief PCs that it the SOH check will be automatic for, but only after a failed save.
So, you take an attack plus a bonus action and need a failed save, plus possibly a slight of hand check to do this and you have to move right up to the enemy to do it. If someone else is going to do the grapple, instead of the Rogue, then two of you are going to need to move up to the enemy to do it. And no matter how you slice it there is a minimum of one attack plus one bonus action to do it.
Meanwhile you could throw a net on him, do it with a single failed save and no need for another check, do it from further away and do it with only one attack without a need to use bonus action.
I don't believe this is something you have done repeatedly in game. How many times have you or a member of your party bound an opponent with a Rope, Chain or Manacles in play by a Rogue as a bonus action in combat? I've seen it done once in two months and around 30 sessions since the 2024 PHB was published. I have seen a net be used more times than I can count.
