Disguise Rules wrote: Here are the basic rules, boiled down to their purest form. Consider this the guiding principle for disguises, or any other form of hiding your identity from someone.
1. The PC trying to keep his/her identity hidden, is the one who must make the most effort. The less effort put into it, the less likely the disguise is to work.
2. The PC who is trying to identify another character can only 'recognize' items, mannerisms, voices, (anything else that fits here) if they have interacted with them before.
Specific Disguise Rule Clarifications
1. Items that are +3 (or +3 equivalent) or higher are considered unique enough to be identified. You must remove all identifiable gear from your character if you want to remain in disguise.
2. Voices must continue to be altered, by the character speaking, to remain a valid part of the disguise. There are no items that will disguise your voice. Stating once at the beginning of a conversation *Muffles Voice* is not enough.
3. You cannot disguise your voice while spellcasting. If a character hears you casting, and they can recognize your voice (see the main rule above) then they can talk with a DM about ICly identifying the disguised character. A PM to both the other player and DM is preferred if a DM is not with you IG.
4. If you are using the Silent Spell feat (i.e. casting a spell with Silent Spell meta-magic applied) then you cannot be ID'd by voice, nor can you be ID'd by the fact that you are Silent casting.
5. The CEP Shadowed Hood is treated in the same way as a helm, as long as it is used in conjunction with other disguise practices. A hood alone will not be a strong enough disguise to protect a PC's identity, but is perfectly valid as a portion of such.
6. Shadowshield is considered a Shadowed Hood for disguise purposes, obscuring the facial features of characters affected by it. Shadowshield has the additional character of, if the spell is visible to a player on his screen, obscuring the color but not the character of avatar-visible items such as armor, robes, wings, cloaks, weapons, and helms. It does not obscure armor for ID purposes under the disguise rules, nor does it obscure IDable items under those same rules.
7. Barkskin would be slightly less effective then armor/helm. You wouldn't see the color of someone's armor, helm, etc... But you'd still see the general design of it. Same goes for the face, it would still be the PC's face but harder to make out fine details. Barkskin alone is not enough to be considered a disguise.
8. Stoneskin does nothing disquise wise. The same goes true for any spell that doesn't have a lasting VFX.
9. You cannot identify a character by smell.
10. Your Animal Companion cannot identify disguised characters for you.
11. You cannot disguise yourself as someone of the opposite gender.
12. You cannot run across a transition and change clothes (or change forms), the transitions are an OOC factor of the NWN Engine.
