4e Chaos Scar
Eldritch Artifacts are alien technologies that perform similarly to many magic items. however the use of these items do not count as a player’s magic item usage. An arcana check must be preformed before each use to determine if the alien technology can be activated by the play. On a successful check the item may be operated on that turn by whichever action is required. A failed arcana check may trigger an eldritch anomaly in which injury to the operator may occur.
