Study

For obtaining or refreshing knowledge of spells, see spellbook.

Study is a status property that appears in dNetHack, notdNetHack and notnotdNetHack. It can be inflicted by monster attack effects, as well as the use of specific items.

Description

A hero or monster subjected to an attack with the study property will become studied - this increases the accuracy and damage of attacks against a "studied" target for a certain amount of turns while reducing their effective AC and damage reduction. The damage dice of a study attack determines both the amount of turns that the target is considered studied for and the amount of extra damage taken from attacks; the amount is also added as a flat bonus modifier to accuracy for monsters attacking a studied target.

• Sanity-related
  • The "overlord" madness from killing Asmodeus, which has a ¹⁄₉ chance of rolling against sanity: failing this roll inflicts 9 turns of study among other effects, and has a secondary ¹⁄₁₁ chance of initiating a second check against sanity; failing this check inflicts an additional 99 turns of study among other effects
