Dear lord, there are tons of animated weapons. (Sky?) If I never see one again I'll be happy.

If acroliths are the floating skulls; too many of them too. A - Vunkerl and A - Konschtat has more than I can handle.

The reason though that acroliths and ruszor are so scarce is because they were only added in WotG and no one really cares about that content.
