Mutations (Spoiler)

=== Mutations (spoiler) ===

=== How can I get mutations? ===

1. By being a Beastman - they get one at the start of the game.
   Thereafter, every level they have a 20% chance of gaining another.
2. By casting the Chaos Spell - Polymorph Self. Polymorph self
   does 1 or 2 effects, randomly with a 3-in-14 chance of getting a
   random mutation each time.
3. By using the Polymorph Self mutation. Polymorph self does 1 or 2
   effects, randomly with a 3-in-14 chance of getting a random
   mutation each time.
4. Possible result of failing to cast a Chaos spell
5. Having your sanity blasted by an Eldritch Horror
6. Possible result of failing to cast a Death spell from the
   Necronomicon. (Chance of same effects as being blasted by an
   Eldrich Horror)
7. Being hit by Chaos or by Toxic Waste without Chaos resistance
8. By gaining a level as a Chaos Warrior as your Chaos Patron may
   grant you a mutation as a reward
9. By gaining a level if you have the mutation "Chaos deities
   give you gifts" as some Chaos patrons give random mutations
   as a level gift now and then.

Note: Not all mutations are equally likely although the variance is
small. In addition, Vampires get "hypnotic gaze" more easily than
other races, Imps gain horns slightly more often, Mindflayers are more
likely to be given tentacles, Yeeks have a good chance of getting the
"Shriek" ability and Beastmen the ability to polymorph themselves.

=== How can I get rid of mutations? ===

The only ways to *get rid of* mutation(s) are:

1. Quaffing a potion of New Life
2. One of many possible effects of casting the Trump spell - Shuffle
3. Getting another mutation that cancels the mutation out
4. Using the services of the Chaos Tower
5. The Polymorh Self spell or mutation may occasionally remove a
   mutation
6. Getting the "You feel strangely normal" mutation gives a chance of
   removing mutations (including itself)

=== What do they do? ===


First of all a warning - Zangband 2.2.2d introduced a penalty for
having too many mutations. The first few are free but thereafter
your regeneration rate is reduced as further mutations are added.
Beastmen are largely exempted from this but, strangely, Chaos
Warriors are not.

There are four kinds of mutations: activatable mutations, randomly
activating mutations, 'continuous' mutations and melee-attack
mutations.


--- Activatable Mutations ---

There are four important statistics for activatable mutations: (1)
the cost (in mana for spell casters and hitpoints otherwise) to use
the power gtranted by the mutation; (2) a stat which is used in
determining your chance of success; (3) the minimum level required
to use the power; and (4) the 'difficulty' of using the power.

Activatable mutations are 'activated' by pressing 'U' or 'O' from
the original and roguelike keysets respectively. Before using these
powers you must first pass a success roll. The actual calculation
of the fail rates for using the activatable powers is very messy
but a good rule of thumb is if the relevant stat is below the
difficulty (18/50 --> 18+50=68), you have little chance of success.

=== Which mutations 'cancel each other out'? ===

Gaining certain mutations may remove other ones. For example, if
you are moronic and gain "computer brain", your moronic mutation
will be gone. Later in the game, you can become a moron again, and
loose "computer brain" in the process. These cancel each other out.

A full list of mutations that cancel each other out is as follows:

1. Computer brain and moronic.
2. Puny and superhuman.
3. Iron skin and either scales,rotting flesh or warts (getting
   iron skin removes all the other three, getting one of the
   others removes iron skin).
4. Rotting flesh and regeneration.
5. Cowardice and fearlessness.
6. Limberness and Arthritis
7. Beak replaces Trunk and vice versa
