Disguise system

Introduction - 21/09/2016 version
The disguise system allows you to change your name, your gender and your race. The effectiveness of the disguise is tied to your disguise skill, some spells can also add a magical component to disguises. Seeing through disguises depends on either your spot skill or your sense motive skill.

Seeing through magical disguise
If there is a magical component to a disguise it must first be identified before having any chance to see through a disguise.

There are two spells able to see through the magical component of a disguise : Detect Illusion and True Seeing.

The system looks up the caster level of each spell and keeps the highest, if the caster level of True Seeing is inferior at 16 it isn't considered, let's call that DetectorDC.

If the diguised creature cast Non-Detection on itself then there is a DC check as follows :

DetectorDC + d20 vs 11+caster level (+4 if cast on self)

If the detector beats the non-detection DC then the magical component of the disguise is pierced.

If the magical non-detection is a success the disguised PC will be informed.

Disguise
Disguises can be more or less difficult : disguising as another gender incurs a -4 penalty, diguising as another race incurs another -4 penalty, changing name doesn't incur any penalty to disguise.

Your disguise score is : disguise skill - penalties +d20

Using spells do not change that part.

Seeing through a disguise
The base disguise score as explained above is used then modifiers are applied, there are two kinds of modifiers : distance and armors. The further away you are and the more armored you are the more difficult it is to see through the diguise.

This is a spot or sense motive DC versus a modified disguise score.

No face covering + gender change or race change : 25% disguise penalty

No face covering + gender change + race change : 50% disguise penalty

Using light armor or clothes :

Race change : -3 penalty

Gender change : -4 penalty

No face covering : -4 penalty

Face covering :

Gender change or race change : +20 bonus

Gender and race change : +10 bonus

Distance and light conditions are significant :

Night + 35f distance : +35 bonus

Night + 30f distance : +30 bonus

Night + 24f distance : +25 bonus

Wearing medium or heavy armor and face covering head slot gives a +30 bonus to the diguise DC.

Face covering head slot gives a +20 bonus to the disguise DC if you're not wearing clothes.

Using a medium or heavy armor gives a +15 bonus to the disguise DC, Light armor gives +10, clothes don't give any bonus.

Wearing only face covering head slot and clothes gives you a +5 bonus to diguise.

Then it are two spot rolls (or sense motive, whichever is higher) +2d10 against diguise score.

Two rolls are made, one to see if the gender change is noticed, the other to see if the race is noticed.
