|This spell uses the bones of a skeleton (or similar materials: the rigid exoskeleton of an insect, for example) to dispense a lethal spray of slicing fragments, allowing its caster to dispense with conjurations in favour of necromancy alone to provide a low-level yet very powerful offensive spell. The use of a large and heavy skeleton (by wielding it) amplifies this spell's effect.|
Bone Shards was a level 3 Necromancy spell which turned a wielded skeleton (two-handed weapon) into a blast of fragmented shards. Damage dealt increased with skeleton weight, but wasn't very impressive.
