This will work assuming you don't already have the achievement and you haven't done a wicked weave attack yet using a dodge offset. Use the
for a punch and
for a kick and hold
till you start firing while also engaging
or the dodge offset with the proper timing. At the end of the backflip of the dodge offset, you should press
, which will cause a blue hand to punch towards where you're looking if you do it right. The first time you do this, you'll get the Wicked Weaver achievement. If you get the timing right, you can repeat this fast. Doing it 20 times will also net you the Wicked Weave Master achievment.
