(CR) Buffs the siege crossbow

Still nontrivial amounts of recoil & dispersion, but at high skill you can now one-shot zeds using metal bolts. Would be interested in thoughts on how to make this worthwhile under the new aiming system (or that it won't be worthwhile, and should be considered a museum piece).

I like it. The siege crossbow is a huge nasty thing, and its damage output should properly reflect that.

The main way that the siege xbow will be useful IMO is after we add
size-based mods to hit chance, you should be able to hit hulks and
jabberwocks with ease with one of these and inflict significant damage.
The phrase 'broad side of a barn' comes to mind.

Pretty confident we already have size-based modifiers to hit.

[kevingranade]

We might have small size contributing to dodge, but large size doesn't make
it easier to hit.
