So far with my testing which while minimal is effective this is the best strategy for taming. Tame a high HP moschops and pump HP in it till it’s at 10K then heal it, and take it to a place with desmodus. Place it and put around 400 blood bags in it or more depending on your server rates. Once that’s done just let desmodus feast on it till it’s at 100% effectiveness should take a few cycles and it can be time consuming, once it’s 100% just let it eat you and when it drops you the effectiveness might go down but just let it eat the moschops and rinse and repeat and then boom, Done
