So, I just crafted a Freezing Vaporizer MKII.
It got a Unique Variant.
It got Attack Speed Increase (IAS) Medium.
I have no idea what that means on a bomb, I looked it up on the wiki also. Does it just mean I can spam attack to see my Knight waggle it around faster?
You'll be spending less time on the recovery frame after you planted a bomb.... pretty much means you'll get about a friction of second less spent on getting up after setting the bomb.
