also remember that pet potencies are not the same as our potencies. i cant use the egis as an example here but i will use the fairies, since i know them a bit better. Embrqce has a potency of 300 and so does Adlo. but Adlo, at least for me, does about 2500, where as Embrace does a little less than 2000. that means the spell is only 80% as strong as my spells. while the percentage might be different, its the same thing for the egis.
