<p>I always assumed Zauberbiests were capable of enhanced strength and endurance but either had limited or lacked altogether magical capabilities, whereas Hexenbiests are capable of great magic (something similar to the Naiads where all males were sterile but females weren't, only in this case it is magic). Sean has never used magic, but since Zauberbiest means warlock maybe they do have magic of some kind.
</p><p>Sean as you mention is half human and thus probably does not have the potency of a full Zauberbiest, but Diana is only three quarters Hexenbiest and still has greater powers than her mom thanks to the ritual Adalind went through to get her powers back. At this point anything is possible. Kelly we know could turn out to be a Grimm-Zauberbiest hybrid, so it would be ineresting to see how compatible those sides are with one another, and what effect they will have on one another. Hopefully we'll get more details in future episodes.
