The Administrator is an Investigator affiliated with the Triad. The role can investigate a target every night to determine crimes pertaining to the target's role or to learn the specific role of the target
The primary strategy for an Administrator is to determine which players are powerful Town roles and thus have them killed at night.
An Administrator may also choose to act as an Investigator on behalf of the Town, helping to find Neutral Evil or Triad roles.
Advanced strategy: An Administrator can claim there is a Forger in game, after he pretends to have found a Triad/Mafia role and has a Townie lynched.
If you have convinced the Town that you are an Investigator, you can use your authority to clear other Triad when they are detected by the real Town Investigative roles by claiming that must be proof of a Forger. For example, if a fellow Triad is discovered Night 3, you can claim that you checked him Night 2 and he was clean, so that's evidence of a Forger and your fellow Triad must be innocent. If a Witch is possible and the role is set to *not* tell people when they are controlled, you can claim the Townie must have been witched. This information can also throw off the Town into believing there is a Forger when there may not be, thus confusing their attempts to deduce the Triad.
