Add a crossbow in the form of a unique bow

The Cho Ku No or Chinese repeating x-bow was able in the hands of a skilled user to fire 10 light bolts in 15 seconds.. Now this is nowhere even close to what barrage can do. Also it had poor armor penetration and range and accuracy compared to your normal x-bow.

op...

Not bad at all, and I also like the " % to Knockback on hit" implicit suggestion.
Imho should also have "5% less move speed" (heavier) and somehow you wouldn't be able to use barrage with it - not that it would be op, just isn't right...

Also after seeing some crazy balista builds (see ranger build list for details), the stats on OP would probably need some nerf.

This crossbow has 550 pDPS, which is worse then a top rare bow. That rare bow also potentially has high crit chance and crit multi. As such, this weapon wouldn't make any top-build stronger. It's a bit like a Marohi Erqui: unique, specific and end-game viable, but easily overclassed by very good rares for most builds.

If Ballista builds are so crazy, then ballista should be nerfed, not this unique...

I'd rather see a regular cross bow base type than a single unique. And yes, Siege Ballista is pretty damn cross bow like, so I'm no longer sure that arguments that "crossbows don't fit in this universe" type arguments hold up.

The animation would be a cost. A reason why it won't happen over-night. But also a reason to consider doing it as a regular base type as opposed to a single unique, in my opinion.

I'd recommend something along the line of "Rate of fire depends on Strength."
