Tempest Runestone

Monsters struck by a melee (not missile or spell) attack under the influence of this rune lose all their Shock immunity/resistance. This loss of Shock resistance applies to attacks by anyone, not just the user of this rune.

Runestones are single use items that are turned in to the coach prior to starting an adventure. The effects get added to your overall stats. One runestone may be used per adventure. However, up to two additional Rare/Ultra Rare runestones can be attached to one weapon (or one runestone each on two different weapons) if the player possesses a Runestone Fitting Base (one per additional runestone) and presents it at the beginning of the adventure with the additional R/UR runestone(s) of choice. Attaching the R/UR runestone still requires the player to turn in the R/UR runestone token, but the Runestone Fitting Base token is not turned in.
