I've been trying to establish a wolf pack in one of my bases by shipping a pair of wolves by sea. Once I get them in their pens to breed, it seems a bunch of trolls show up. I have to run away and one Troll may follow, but the rest head right for my wolves and wipe them out.
Can we get some sort of effective defence ? Maybe a Ballista that becomes available with the Bronze tech that can kill a troll in 2-3 shots . We could build towers to mount them or leave them on the ground.

I just go toe to toe with the trolls and kill them in melee. If you are getting wolves and in the silver age, trolls shouldn't be a problem to parry if you can't dodge.
