[RPG] If an NPC and a PC roll identical initiative who goes first

dnd-5egm-techniquesinitiative

Normally, when 2 players roll identical initiative in combat, they decide between themselves the order they do things in and then stick to that on subsequent rounds.

How should the DM handle it if the NPC rolls the same initiative, especially if they are in combat directly with the player who rolled the identical initiative?

If rolling bulk initiative for a group of NPCs, how should identical rolls with players be handled here? It feels like a lot can swing on whether the GM chooses for the group of NPCs to attack the player before he can decide his action.

Best Answer

In the rules for initiative, the Player’s Handbook suggests the following:

If a tie occurs, the DM decides the order among tied DM-controlled creatures, and the players decide the order among their tied characters. The DM can decide the order if the tie is between a monster and a player character. Optionally, the DM can have the tied characters and monsters each roll a d20 to determine the order, highest roll going first.

The DM decides, and the PHB gives a suggestion how they may make that decision.

Additionally, the Dungeon Master's Guide has many initiative variants that come with their own methods of resolving ties.
