How to get an enforcer:

1. They aren't tamed, but they can be crafted.

2. If you crafted them using the engram, they'll be pretty bad.

3. If you kill wild Enforcers instead, They'll drop a better blueprint for unassembled Enforcers which range in rarities just the same way saddles, tools, and weapons do.

-Higher Tier unassembled Enforcers will spawn with more extra levels and better stats.

-I gotta warn you, they are really expensive to make.

-They can climb cliffs or walls.

Hope this helps!
