Is that similar to bear-blasting?
Close but it made acrobatics more fun, the aim was to avoid taking a hit from the rats AI leap attack, which was always preceded by a squeek.
Due to their scale if you timed it right you could avoid their attack.
Not many rats where outside however, but standing in front of a pit trap or any trap really made up for it, so you get them to fall down a spiked pit, or get shot at ( if you triger that trap yourself ).
Then you mix in sneak.. where you have to get right up behind a rodent the leap over them so they detect you after.
