I'd say there's a minor fluke in the way offering a draw works in Behemoth chess, cause when you offer a draw, your opponent gets to accept it in a different situation (with more information) which kinda makes offering a draw quite a bad idea, even in equal positions. (I'd say in about every other game, your opponent has to accept or decline the offer in the same situation as it has been issued.)

Say there are only the kings left, and the Behemoth is not attacking any king, its quite an even position, but offering a draw gives a lot of advantage to your opponent, since he gets to see where the B. goes before deciding, and will decline if the B. attacks only your king and accept if it attacks only his king.
So with reasonable players, the draw feature is quite meaningless in such situations, even if both would prefer a draw.
Maybe it would be a consideration to relay draw offers in Behemoth chess before the Behemoth move is executed,
on the other hand this is probably just a minor incoherence not worth the bother, but it was annoying me once or twice when i would have liked to have a draw, but offering one would have been unwise.
