Okay so I found this out about bolas. If they teleport to you they break out of bolas, but if you are close when you bola it it will just try to walk to you and won’t teleport so it will stay in the bola.(90% sure, this is from tests not facts)
When you have an Enforcer and level him up he can carry quite some weight, has a lot of health (though you shoulden't try to kill anything higher than a corrupted Rex),and he can do a lot of damage. You can even build your fort up high and jump down with him 'cause he has no fall damage.
