Lip Reading

Advances
Perception
Use the Lip Reading skill to “listen in” on conversations that take place out of earshot. To use this Skill, you must have an unobstructed view of the speaker’s mouth and you must also be able to understand the language spoken. Distance is the biggest factor. The further away the subject is, the harder the Test. The base Difficulty is Challenging (+0), but it worsens by one step for every ten metres of distance. Note that equipment that magnifies vision can be used to offset this penalty and even provide bonuses.
A successful Test reveals the general gist of the conversation, such as the person is talking about the weather, new tariffs at the space dock, and so on. Each degree of success reveals more specific details.
A Lip Reading Test is a Full Action, though it lasts as long as the target speaks.

Lip Speaking

You may use your Lip Reading skill to communicate discretely with another person in your line of sight, either hiding coded messages in regular conversation or mouthing a message to them. You only need to make a Lip Reading Test to hide words in normal conversation, not to simply mouth a message, but the recipient must make a Lip Reading Test either way to successfully interpret the message. If either Test is failed then the message is not conveyed properly.
