Rabbat hunting multiple times

[DOUBT] good night, i would like to know about Rabbat's special ability, in case if i hunt with her and move the blood to the pool then use freak drive and hunt again, i can use her skill again and move the blood to the pool again?

Yes. Every time she hunts, one of the blood she gains, she can transfer to your pool.
It is not uncommon to se Rabbat being Tempted several times by the owning player, to force her to hunt multiple times per turn, gaining one pool for each hunt.
