Squire weapon - negative knockback

[darlingm]

I've been looking around for if negative knockback is any different than zero knockback, and have only found a bunch of threads with unsure and conflicting information.

A trans tower sword I got the other day has -110 knockback. I've leveled its damage stat through 181/227. Wanted to make sure that I don't need to get the knockback to zero for any reason. (I know if I hit zero and close upgrading, the stat goes away.) I'm hoping its effectiveness caps low at zero...

In NM, knockback is nerfed to the point you need a high amount to actually knock anything back... basically, if you start at negative, there's no real reason to upgrade the knockback. You won't get any benefit out of it.

I actually did find a use for knockback. In Uber MonsterFest, sometimes mobs would get trapped in the fan. If you don't know what I"m talking about, just assume a mob is floating. You can float next to it and attack it. If you had any sort of knockback, it would fall. But now, my new tower hammer has neg knockback, it doesn't fall, I have to manually kill it.

That, and knocking mages off of ledges is about the only use I found for knockback, and for that I can circle slice. (can't circle slice in mid-air for the example above).

(I guess this post was a bit off-topic. I have no idea what neg knockback does. I assume it just is equal to 0.)
