Most seem to underestimate reaper kings, which if you aren't familiar with them is understandable but let me tell you this thing to the second strongest creature if not tieing with the giga unless the giga is bred but kings are way more mobile, have a base resistance of 70% but increases to about 83% riding it with full imprint and can easily get its health to upwards of 30k and it's damage 900%+ which with imprint is the equivalent of a giga with 200% dmg which may not seem like much but that's still 900+ raw damage and that's a lot for such a mobile creature..
They can bunny hop over large distances, are faster then most large carnivores, can solo a wild giga, and are relativly easy to get. 10/10 get a large army of these (7-10) and you will be unstopable. My 2 strongest have 50k hp and 1200 damage, and the other has 80k hp with 700 damage, and they are op, if u dont have one, than get one. (Or several)
