What do the +x, +y values represent on weapons?

Question

My guess is...

x = accuracy y = damage

...but I figured I'd ask just to be sure.

I checked the wiki pretty thoroughly but couldn't find any info on these two values.

Answer 1

You guessed right.

The first + is a bonus to your accuracy, meaning the chance that your attack connect with the enemy.

The second is a damage bonus, which is, of course, only applied if your attack actually hit the enemy.

Note that missiles can only have an accuracy bonus, not damage.
