This small product does a decent job introducing the concept of a substandard or faulty magic item. The rules to make a substandard magic are simple to add and not anymore complicated than the existing magic item creation rules. Each school of magic has a 3 possible backfires when a faulty magic item is used with most of the effects being temporary in nature.
I hope to see more of Bret's work for Ronin Arts in the future.
LIKED: The mechanics for the introduction of substandard item creation is simple to use and does not require the addition of a bunch of new material.
Rules for damaging substandard magic items
DISLIKED: I would have like to see an increased number of choices for each school of magic.
