This translucent green oil sparkles with tiny, Blightsteel Ingot Flakes.

The oil can coat one slashing or piercing weapon or up to 5 pieces of slashing or piercing ammunition. Applying the oil takes 1 long action. For 1 minute, the coated item is magical and deals an additional 1d6 necrotic damage.

If you drink the oil(for whatever reason) you take 6d10 necrotic damage. If you are resistant, immune, or are healed by necrotic damage, you gain 1d8 levels of exhaustion.
