You are skilled at changing your appearance.
Your Disguise check result determines how good the disguise is, and it is opposed by others’ Perception check results. If you don’t draw any attention to yourself, others do not get to make Perception checks. If you come to the attention of people who are suspicious (such as a guard who is watching commoners walking through a city gate), it can be assumed that such observers are taking 10 on their Perception checks.
You get only one Disguise check per use of the skill, even if several people are making Perception checks against it. The Disguise check is made secretly, so that you can’t be sure how good the result is.
The effectiveness of your disguise depends in part on how much you’re attempting to change your appearance.
1 These modifiers are cumulative; use any that apply.
If you are impersonating a particular individual, those who know what that person looks like get a bonus on their Perception checks according to the table below. Furthermore, they are automatically considered to be suspicious of you, so opposed checks are always called for.
Usually, an individual makes a Perception check to see through your disguise immediately upon meeting you and every hour thereafter. If you casually meet many different creatures, each for a short time, check once per day or hour, using an average Perception modifier for the group.
Creating a disguise requires 1d3 × 10 minutes of work. Using magic (such as the disguise self spell) reduces this action to the time required to cast the spell or trigger the effect.
Retry? Yes. You may try to redo a failed disguise, but once others know that a disguise was attempted, they’ll be more suspicious.
