Half spell damage is an extrinsic property that occurs in NetHack, and halves any damage taken from spells while reducing the impact of certain other spell effects.
This property is conferred 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.
