Ring of the ram

A ring of the ram, also referred to as a breaker of castles, was an enchanted ring that released a blast of pure force energy that resembled a spectral ram's head.

Effects
Upon pointing their hand in a certain direction and uttering the command word, the wearer released a destructive eruption of energy that was capable of destroying walls, castle gates, or the bones of the wearer's foes. The blast had an effective range of approximately 60' (18.3 m).

These rings possessed three charges and recharged every morning at dawn. Additional charges could be used upon the ring's use, increasing the strength and potency of the blast.

The effects of these rings were recreated by the arcane spell, battering ram.

History
Pal Verbosh, one of the deadliest pirates of the Nelanther Isles had his ship sunk by a rival pirate who was wearing a ring of the ram.
