All new genesis 1 and 2 animals such as x- or r- types have max level of 500. This includes maewings , magmasaurs…
since you can add 88 levels to all creatures now, not just the genesis animals- the new limits for levels at hatch and birth is now 362 for all non-genesis animals, and level 412 for all x,r, and new animals from genesis.
In the old days the game let us level animals above 450 but those would blank after a server restart. The game now won’t let you accidentally level past the 450 limit if the animal is held to that limit.
you don’t have to worry about this problem anymore.
if there’s a map that doesn’t obey those rules, then it would be a big problem and I’m pretty sure it would have come up on these forums by now.
