    Mind fog, similar to Biowares.

    Ok, On Enter, we save against the spell and if fail, will take -10 on
    will saves.

    On Exit, if they still have the spells effects, will have the permament
    effects removed and have tempoary ones added.

    If, On Enter, they have tempoary (not permament) effects only, of this spell,
    they will make a new save and if failed, put permament effects on and remove
    the tempoary ones.
