Relic

root@eridian-db:~$ cat description.txt

A basic Eridian relic that boosts shock damage. More broadly, relics are passive gear pieces that increase one or more character stats, ranging from elemental damage and survivability to utility bonuses that are hard to find elsewhere.

root@hyperion-db:~$ cat notes.txt

For relics with percentage-based bonuses, the final value depends on both item level and grade. Grades range from 7 to 15, so a higher-level relic can sometimes roll weaker stats than a lower-level one.

That same scaling rule applies at Overpower levels, and the strongest rolls usually come from the highest level with grade 15.
