Interacting With Townsfolk (NPCs)
Interacting with townsfolk is important in Diablo II. They tell you about
relevant events and people in the world of Sanctuary, and some offer goods or
services to assist you in your adventures. Urgent News - An NPC with an
exclamation point (!) overhead has urgent news for you. Usually, the news is
important information about completing your quests and advancing in the game.
You should approach and talk to any townsfolk with an "!" overhead.
