This addon automates Delve interactions including tier selection, power choices, and NPC dialog. Set your tier level and enable auto-entry and the addon will automatically set the Delve to that tier and move you in inside as you approach the entrance. Turn on "Automate Gossip" and the addon will attempt to automate interactions with NPCs inside the Delve. Turn on "Automate Delve Powers" and when you come upon a Delve power the addon will automate the power selection window.
