max maturity without plates : Oro, Zadul, Nusul, Wombana, Hadraada. Max maturity with 5b's : Tiarak, Mutated Oro, Bokol, Kadra, Madana (might want a healer for these, or different plates) Low maturity without plates : err... well... I got an excel sheet with all the missions and it is all set on max maturity hunting, so I can only give you information on that. Oweko low maturity's are ok-ish with viceroy, but it has been a while I have been hunting those. Spots can be found easily on entropedia, if you can read the small map, and ofc. the #arkchat. Oh right, you might be able to hunt Huons (with plates) on low maturity. Hope this helps.
