Iron Ring of Power

An Iron Ring of Power is one of a set of ten rings made by Angren, the Metallic Terror. Wearing the ring has the following affects;

The wearer automatically alerts Angren to their location. Angren always knows who is wearing his rings and where they are. If Angren is not alive and a wearer of an Iron Ring is killed, their soul is consumed by the Iron Ring and used to resurrect Angren. An individual who's soul is consumed this way cannot be resurrected until Angren is slain.

Whenever an individual with a class or levels wears an Iron Ring, they gain a level in a class while wearing the ring. They may only select this level in classes they have already taken a level in. If a character is 20th level in a class, gain one of the following benefits while wearing the ring instead.
