I would start going for the apexs or some of the top tier creatures (ie scorp, skoona, indotaurus etc)
Scorpius rex gen3 and indotaurus is very good
Unlock rinchenia first, then work on the missing legendaries
Monolorhino
Oh forgot to mention this but i cant get scorpius Rex gen 3 indotaurus any of the apexes ir erlispyx or monolorion BC i cant do the Raids and i dont have any dna for those creatures (i cant do the Raids BC of school btw)
Indotaurus is worth it if you give it speed boosts
I allready got it like 2 weeks ago
Erlidom is bad
Switch it for that ardentis and level it up
