So assuming the wording does not change, will Razzi be able to spend a TL to reduce an enemy's agility if she attacks them? Similar to how Etahn's ability also affects himself?

Yes. Specifically because it doesnt say 'other friendly ship'. That is the distinction.

Thought so. Figured I'd ask before I fell in love with a build prior to release

Also it does not say once per round, and so if you have two target locks (with weapons engineer) you can do it for two different attacks. I think Latts is going to get lots of use from me compared to the other 666s

Razzi with HLC, K4 and 4x Pirates with Feedback is 99 - add Greedo or Inertial Damps if you don't want to bid for initiative.
