Ugh, these demonic creatures are such ghastly things. Kain is definitely more than glad he's got some help here... he'd have been swiftly outnumbered if not. Not only does he have to get closer, he can't really do much about that rift until he's not being attacked. So he focuses his attention on the demon coming after him, giving it an upward slash of his lance at it as he leaps upward, then striking down as he descends. It weakens the demon, but he's got to keep on it if he wants to get rid of it entirely.
