Sucker Punch opens up a brand new way to play!

[Green Raven]

In the original, there was a perk that gave bonuses to grenades if you had a free off-hand, but who was going to go there? You went sword and board if you were defensive, two handed for damage dealers, and dual wielding for dagger wielders.

But Sucker Punch is so devastating that I find myself building my charachter as a single sword duellist

Sucker Punch as always been in DoS2 unless it's been updated.
I've had my characters unequip their weapon to use a sucker punch for more cc.

[Firecam]

Yup it's very effective with dual daggers.

[Cutlass Jack]

Not really a new way. You always could do it even in original. The only change to sucker punch was a slight damage bump.

One handed grenade throwing, scroll spamming Sucker Puncher was always a favorite novelty build of mine. Maybe not as overtly powerful as other builds, but surprisingly versatile and fun when you're willing to use consumables.
