Shards will grant power, but at a cost. Those who have spent their lives cataloging shards have come up with a common classification. Spell level determines the shard’s power class (from least to ultimate as above). The kinds of spells it grants tend to be part of a specific eldritch horror’s domain list. For example, if one finds a shard that grants 0 to 3rd level spells from the divination and/or illusion schools, one could name the shard a “Minor Shard of Blibdoolpoolp”, or a “Minor Shard of Volgna-Gath”.
