Nightfall
Sage of the Scarred Lands
I personally have no problem with either spells, since I would most certainly require a spellcaster to find a creature with that much str and get blood from them BEFORE they could gain such spells. As for a spellcaster getting Belsameth's Blessing, I'd prefer a much interesting approach. One, they have to find not only the tuft of fur from the creature, but also get it's heart as well. This way they have to earn it each time they want to use it. (Since I'll rule they can't use the heart again.)
