Glad you like how they are working out
What size game did you use them in? What did the delgon force look like?
We've been trying out two different variants of the KJs: First up is the version as shown, and you interpreted it correctly.
The other version we've been trying uses a similar approach to the grishak (and is similar to your option 2) - the benefit applies in any combat where only oran are rolled successfully.
In both cases the skill works against shooting.
What do you guys think? I'm erring towards the second option at the moment, but nothing is finalised yet!
