Roam Linden:
How do I coral them? Between Stalker, discover Dino’s and such I should have an idea and the others should help direct them.
Generally one would have to be in the sea, and probably do some genetic manipulation to increase growth speed to surround the dinosaurs with coral. :D
But if you'd like to get the dinosaurs to stop, slow down, or trot in a circle until they manage to calm themselves, I'd call that two DT 5 dino interaction rolls (dino behaviors, etc counting as an asset).
