Combat in D&D is a turn-based procedure built to answer a few recurring questions quickly: who acts first, what each creature can do on a turn, how movement interacts with danger, and what happens when attacks, spells, and conditions start changing the battlefield.

Start with order. Initiative and turn order are the backbone. Once the order is clear, the rest of combat becomes a sequence of choices.
Track pressure, not just damage. Position, cover, opportunity attacks, and conditions often matter as much as raw hit point loss.
01

Roll Initiative

Establish turn order so everyone knows when they act and how to time reactions, movement, and support.

02

Take a Turn

Use movement, actions, bonus actions, and object interaction as the build and situation allow.

03

Resolve Attacks & Effects

Attack rolls, damage, saving throws, and condition application change the state of the field.

04

Repeat Until One Side Breaks

Combat ends when opponents are defeated, flee, surrender, or the situation no longer needs initiative tracking.

Action economy decides momentum. A side that gets more effective turns usually controls the pace of the fight. This is why summons, extra attacks, reactions, and denial effects can feel so strong.

Movement is a resource. Position determines reach, cover, line of effect, and whether leaving a threatened space is worth the risk of an opportunity attack.

Advantage and disadvantage simplify many edge cases. Instead of stacking lots of small numeric modifiers, the system often asks whether the attacker or acting creature has an edge or a hindrance.

Conditions change choices. Once creatures are restrained, prone, frightened, charmed, or otherwise impaired, the fight usually stops being a simple exchange of hit points.

Melee and Ranged Pressure

Know when the build wants to stand in melee, kite at range, or protect a caster or support character.

Cover, Reach, and Space

Terrain and placement matter. Cover and line management often decide whether an attack or spell is even worth attempting.

Grapples, Shoves, and Control

Not every turn should be an attack roll. Control actions can reposition enemies or lock down key targets.

Mounted or Underwater Fights

Special environments change movement, weapon use, and tactical expectations. They are worth checking before the session, not during the panic.
