    === Possessors ===

    Description
    Possessors are unusual; they aren't good fighters, and they can't cast
    magic. Their special ability is that of being able to leave their
    bodies and inhabit corpses. While "in" a corpse, the Possessor gains
    the abilities of the monster, and their hit points and the monster's
    are averaged. While in the incorporeal form between bodies, they have
    only one hitpoint.

    Starting Equipment
    A Possessor begins the game with:
        a Potion of Healing
        a Short Sword
        a Hard Leather Armour

    Possession
    The strange art of reanimating the corpse of a monster and making
    it one's own can be of extreme benefit to those skilled in it. The body
    the player possesses can grant powerful abilities, such as increased
    speed, summoning, healing, breathing, and various resistances, and often
    gives the player a large number of hit points. Possessing uniques is
    especially neat.

    Possessors leave their own body by using the 'm' command, and choosing
    "[I]incarnating powers". Lacking a life force to sustain it, a corpse may rot
    immediately when a Possessor leaves it, but a high Possession skill score
    may prevent this from happening. They then become a very vulnerable ghostly
    being which travels to where another corpse is lying on the floor, and
    possesses it by again using the 'm' command.  Once possessed, many
    monster corpses allow the player to perform various special actions
    (such as blinking or summoning) by using the option "Use your [R]ace
    powers".

    All corpses alter the player's melee attacks. When they incarnate in a
    monster that allows the use of a weapon, monster blows are ignored
    totally. When they incarnate in a monster that doesn't allow use of a
    weapon (dragons for example) they use the monster blows and only them!
