Half spell damage

From NetHackWiki
Jump to: navigation, search

Half spell damage is an extrinsic property which halves any damage taken from spells, as well as halving certain other effects. This property is currently conferred only by carrying The Orb of Detection, The Platinum Yendorian Express Card, The Orb of Fate or The Eye of the Aethiopica. Carrying more than one of these objects does not further affect spell damage.
