To make the queue via an npc, the process is pretty easy. First, you need to select your npc by doing Select the NPC: Face the NPC and run the following command to select it:
/npc select
Add the Duels Command: Once you've selected the NPC, you can assign the duels play command. This example will allow the NPC to queue the player for an unranked 1v1 duel in classic mode:
/npc command add duels play unranked solo classic
This will automatically queue the player for an unranked 1v1 match with classic mode when they interact with the NPC.
