  Increase damage to enemies within 13m by 20% (+20% per stack). which boost each individual damage instance without modifying the strength of the incoming attack, Breaching Fin does modify the incoming damage which means for long proc chains its effect can double dip. For example, Commando doing 12 damage with his primary has it modified to $12\times 1.1=13.2$, which proccing a Charged PerforatorCharged Perforator

Impressed? I know you are.
We finally cleared our grid, but man did it put up a fight. We lost James and Kight. This fin knocked them off the U.E.S.S. [REDACTED] with so much force we heard them hit the water in pieces. At least it was quick.

There isn’t a speck of land on this blasted planet but now it’s safe enough to build our first dock. It’s not land, but it’s a step up from this flotsam. I won’t miss giant sea creatures bumping the ship in the night, or losing my lunch to this damn swaying.

Get us a good commission for it will ya? And send down some playing cards, the silence is killing us.
