Chatting

(C)hatting allows the player to attempt to talk to another entity. The player may talk to anything or anyone regardless of its disposition to the player, producing a variety of responses.

Chatting has a few important functions:

• Allows the player to receive and turn in quests from important NPCs.
• Request services from healers, smiths or tailors.
• Issue commands to intelligent allies.
• Science talking to boost your INT and WIS.

Outside of these functions, chatting with an entity simply produces amusing flavor text.
Be warned that although almost every monster produces a response when talked to, some are unable to chat if you polymorph into their form.
