49. Is Battlemasters manouver "sweeping attack" working together with GWM to second attack? I mean if is using -5/+10 in base Attack Is dealing 1d8/10/12 + 10 dmg?
If yes, than this manouver worth to take, when I have GWM
Yes, they stack. The extra attack you can get from GWM uses your bonus action, whereas "Sweeping attack" is just a regular attack but with multiple targets. You could make multiple Sweeping stacks in one action with your "Extra Attack" feature.
Given that the extra target only takes damage equal to your superiority dice (so you can't attach riders to it) I would still rate it "poor" though.
Last part was answer I wont. So second target get only manouver sice dmg And no +10 even I used it for main target.
That would be my reading. And no extra sneak attack/barbarian rage/zealot etc damage for devious multiclassers.
I would infer from this Sage Advice that
@Paul Farquhar's reading is probably RAI, FWIW.*

However, GWM introduces an additional question not raised by Dueling: if you disallow the +10 to damage against the secondary target, do you still apply the -5 to the attack roll?
Personally, I'd rule the other way, having the -5/+10 apply to the secondary attack as well (and the same for the +2 of Dueling for that matter). IMO, several considerations point in that direction.
- For me, the obvious fluff for GWM is that the character is swinging harder, but, as a result, less accurately. Removing the damage bonus from the damage to the second target, to me flies in the face of that fluff. The description for Sweeping Attack literally says that the effect on the secondary target is part of the "same attack". If that attack was made harder and less accurate, then it's harder and less accurate. Period.
- The issue of the the -5 makes both alternatives to keeping the -5/+10 suck. For the secondary target, removing the +10, but keeping the -5 just seems unfair, but removing the -5 means that after cleaving through one target your strike became somehow .... more accurate?? Blech.
- GWM's -5/+10 option is not a limited use ability. So if the strike against the secondary target had been made as a separate attack, the -5/+10 could have been applied without using any more resources. Hence, applying it to the secondary target of Sweeping Attack doesn't seem to me to be providing very much additional "leverage". In fact, it's a bit of a trade-off: if you want to use Sweeping Attack, then the -5/+10 applies to either both targets or neither, whereas if you attacked them separately you could choose to use it on one and not the other.
- Superiority Dice
are a limited resource and Sweeping Attack competes for their use with the other maneuvers the BM has picked. Also, Sweeping Attack can only be used situationally. This means that the GWM/Sweeping Attack combo is unlikely to come up very often, so any argument that allowing the -5/+10 to apply is somehow OP is suspect, at best.
- I don't see any particularly good reasons to rule otherwise.
I would rule the same way for Dueling (Crawford notwithstanding) and bonus Rage damage. However, Sneak Attack and Divine Fury are specifically limited to one creature per turn, and not applying them to the secondary target is compatible with their fluff.
My 2 c.p.
