Multiple personalities

[Everwinter]

I'm starting a new campaign and one of my players wants to have multiple personality disorder. I'm not sure how that should be run and could use some tips on it.

Mutagenic form and Mutate

Try the fluff for that, modifying for how he wants to fluff his personalities up. Just don't bother with the stat bonuses here, but a lower DC will save every now and again when they take massive damage or some kind of major system shock might be a good idea.

Whatever you do, don't get conned into allowing effectively multiple character sheets for each personality, and definitely don't give him "bonuses to compensate".

There are rules for a multiple personality disorder in the Game Mastery Guide. Sounds not so funny .. :)

Multiple Personality Disorder

Type insanity; Save Will DC 19

Onset 2d6 days

Effect –6 penalty on Will saving throws and Wisdom-based skill checks; multiple personalities (see below)

Description

This is a complicated disorder that manifests as 1 or more distinct and different personalities within the same body and mind. The number of additional personalities the victim manifests equals the DC of the insanity divided by 10 (round down, minimum of 1 additional personality). Should the insanity worsen in some way (such as by the save DC increasing), the number of additional personalities increases as well. Likewise, the number of additional personalities decreases as the sufferer recovers and the insanity's DC decreases. The GM should develop these additional personalities.

Every morning, and each time the afflicted character is rendered unconscious, he must make a Will save against his insanity's DC. Failure indicates that a different personality takes over. A character's memories and skills remain unchanged, but the various personalities have no knowledge of each other and will deny, often violently, that these other personalities exist.

Note: If the PC is the target of Greater restoration, or Heal, then they are cured of all insanity.

Instead of the character being insane he could have multiple identities on purpose. I had character who was a spy who maintained multiple covers complete with different personalities and apparent alignments. The characters skills and abilities do not change, just how he presents himself to the world. This does create a weird situation where you have to role-play a character who is role-playing.

[Zahir ibn Mahmoud ibn Jothan]

I think my method for handling this situation might be to have the character create a set of base stats using a point buy.

And then go one of two routes:

Either have the other personalities be templates applied to the base character, OR have the character's physical stats remain unchanged, but have the mental stats be possibly different, but using the same point buy that is left over from the physical stats.

So that accounts for some of this. The danger is that the Player could then have a cleric personality and a Wizard peronality, and by switching personalities gain more spells than is acceptable, that sort of thing. I wouldn't allow that. Either have the personalities think they were something else, but be dipping into the same resource pool for spells and such, or enforce some complete randomness day by day, or whatever as to which personality is in charge.
