Resonate is a condition that the Hadross applies to others. There are several abilities that activate when the model you are engaged with or are near has the resonate condition applied to them. By itself, resonate does nothing
Yeah, I read that too. You would have expected a better explanation as to what it is if you were going to make it such an integral part of their make-up. Some fluff, something.
I think it is some kind of sonar effect and when the fish people make a sonar call and something pings(resonates) the rest of the fish people attack like well hungry fish
We shouldn't have to guess. How hard is it to fit a description in the book? It would be great if someone from CMON would chime in on this. It doesn't seem like anyone from CMON even looks at these posts.
I've seen them respond to threads from time to time since shipping started. They are a small number of people and have probably received a backlog of emails. A thread on where the idea for an ability is going to rank low on their priority list. I'm sure we'll here something soon.
A lot of the time abilities will be shortened when they appear on other more basic version of a model. In this case look at the rules for the Deepman Guardian.
