Was chassing the migration trajectory of deepwing brooders and had an idea: give the possibility to put a tracker on leviathan class creature (so for now: deepwing brooders and Collector).
In that way we could have an idea of their position, both to follow or escape then according to our plans.
It could help avoiding that massive Collector stalking before ruins during traversal of the second part of the game, without any need of “fighting” tool.
If prefered, it could have a proximity detection or something like this, not necessary appear all the time like beacons do if it help your design.
