I'm working on BE quite a while now but i still dont really understand what all those stats on the templates mean.

What do i do to give it more HAM or more damage?
Also when i tried arachne warrior dna whom has light armor my crafted pet has no armor, how can i fix this?

When i try mixing dna from different creatures i usually get a wierd and unbalanced result like 2k life and 6k action.
And what i really dont understand is how to improve already crafted creatures by sampling them, my pets always seem to come out lower then the donor.

I got 3-0-4-2 now, what should i be able to make?
