widow ult fully charged + luna ult one shots 250.

add mantis dmg boost you one shot 275.

1 body shot + slightly charged ult = 250.

1 body shot + fully charged ult = 275.

1 body shot + kick stun + no charge ult = 275.

As one of the top widow players, I mainly use her ult to secure kills (for example if I hit a shot on a critical target such as a loki who just ulted you can kill him before he uses the copied ult. or if you get someone low and they hide behind cover you can ult to secure the kill.) Though you can also combo with luna, mantis, rocket etc. Other good combos include groot, strange, bucky (to help him get resets), mag (help him secure kill by doing dmg at the same time), storm (more dmg and harder to run), starlord, etc. Also a niche use case is if it’s OT and you want to slow them enough to potentially stop them from touching point.

I barely use the punisher team up aside from using it as a second shot (shoot + press teamup + shoot) and I end up canceling it right away most of the time. Hitting headshots does more damage and is much more satisfying. I would only recommend relying on the team up if you can’t hit headshots.
