Cliffhangers are pretty weak enemies. Before you level up it will only take two strikes to hit them, and after one or two levels that number will drop to one. They can absorb some of your HP with their attacks, on ocassion, but the amount of HP that they recover is so small (around 4 HP) that it becomes insignificant. They also sometimes cause poison, which can be a little more important.
