This article presents a detailed, step-by-step walkthrough of the First Edition combat process, using a sample dungeon encounter to illustrate how surprise, initiative, spellcasting, movement, and combat resolution function in play. Where appropriate, notes identify the specific rulebook sections from which each procedure is drawn.

Combat is a central feature of Advanced Dungeons & Dragons (AD&D). Although the rulebooks present combat as an orderly, segmented procedure, the texts themselves contain gaps, ambiguities, and overlapping subsystems that can lead to confusion—particularly where movement, initiative, surprise, and spellcasting intersect. As a result, the practical conduct of melee combat is often left to inference rather than explicit instruction.

Combat is a central feature of every edition of Dungeons & Dragons. In a melee round, combatants jockey for position, missiles streak toward their targets, and spells are unleashed amid the chaos. The rulebooks present this process as orderly and well-defined.

Psionics in First Edition Advanced Dungeons & Dragons (AD&D) are an optional subsystem of mental powers drawn from the minds of creatures. Their inclusion adds a rare and unconventional dimension to a campaign.
