If I had to list my top 5 tames here’s what it would be.

Argy, Otter, Equus, Direwolf, Spino.

Argy above all else because they are :

1.Flyers

2.Can Cary most small-med creatures

3.Hp buff when you harvest corpses

4.Great for fighting

5.Needed for taming

6.Weight reductions galore

7.Mobile smithy

So get a darn argy!
