Under the 2024 D&D Basic Rules, Dodge is not Disengage. Dodge can affect an attack roll without removing the opportunity to make the attack when someone leaves reach. Decide whether the movement provokes first, then work out the roll.
This original scene is for a Dungeon Master using DMGrid. It does not claim the program automatically detects Opportunity Attacks or applies these actions. The rules reference is the official 2024 glossary; check any specific feature that changes the situation.
Establish the scene before moving the piece
In our fictional example, an adventurer is within an opponent’s five-foot reach. They can see each other, the opponent has a Reaction available and no special feature changes these rules. The adventurer has a Speed above zero, is not Incapacitated and uses her own movement to leave.
Ask which action was declared. “I protect myself as I move away” describes intent but does not yet identify Dodge or Disengage. Clarify the decision before resolving the path; do not infer the action from the miniature’s pose.
If the choice was Dodge
Until the start of her next turn, Dodge gives attack rolls against her Disadvantage if she can see the attacker, and gives her Advantage on Dexterity saving throws. Its benefits are lost if she becomes Incapacitated or her Speed is zero.
Our scene keeps the conditions for that benefit. When she leaves reach using her own movement, the opponent can still spend a Reaction on an Opportunity Attack, made immediately before she leaves reach. If the opponent chooses to attack, the roll has Dodge’s Disadvantage in this example without other modifiers. The protection did not erase the trigger.
If the choice was Disengage
Change only the declared action to Disengage. Under the basic rule, her movement does not provoke Opportunity Attacks for the rest of the current turn. Do not resolve the same attack “but with Disadvantage”: under our assumptions, that movement no longer provokes it.
Keep “is there an opportunity?” separate from “which modifiers affect the roll?” If a specific feature changes either answer, read its text. Do not extend this example to teleportation or every kind of forced movement; those do not use the same assumptions.
Preserve the decision in a note
Before continuing turn order, a useful manual note could say “Adventurer’s turn: Dodge; leaves reach; opponent spends Reaction; attack resolved.” For the alternative, write “Disengage; movement does not provoke under the basic rule.” These are authored notes, not DMGrid-generated events.

For this decision, the information that should follow the piece is the actual chosen action and whether the opponent spent a Reaction.
