View source for Good mutations

This is a list of all of the '''good mutations''' which can be acquired. While most of these are useful to any character, some may in fact be significantly detrimental to some builds. Even so, they are included here because "good mutation" is a technical term in the game, not a qualitative judgment. Any of these can be acquired through any source of good mutations, such as a [[potion of beneficial mutation]].

=Offensive=
Some of these mutations will prevent your character from wearing items in certain equipment slots. While this penalty may outweigh the gain your character receives, bear in mind that races which cannot use those slots ([[ogre]]s, [[troll]]s, [[felid]]s, etc.) anyway lose nothing.

===Fangs===
Grants an [[auxiliary attack|auxiliary]] [[Unarmed Combat]] bite attack. Deals (2*Rank+(Unarmed Combat/5)) damage, and stacks with [[Acidic Bite]]. At rank 3, lets you butcher [[corpse]]s with your face. [[Vampire]]s and [[felid]]s start at rank 3. This mutation is mutually exclusive with a [[Beak]].
{{flavour|1. You have sharp teeth.<br>2. You have very sharp teeth.<br>3. You have razor-sharp teeth.}}

===Beak===
Grants an [[auxiliary attack|auxiliary]] [[Unarmed Combat]] peck attack. [[Helmet]]s are prohibited. [[Tengu]] start with this. This mutation is mutually exclusive with [[Fangs]].
{{flavour|You have a beak for a mouth.}}

===Claws===
Improves the damage of your [[Unarmed Combat]] fist attacks and allows them to make foes [[bleed]]. Damage rises with rank. Wearing gloves negates the effects of this mutation; at rank 3, [[gloves]] are prohibited. [[Troll]]s start at rank 3, [[ghoul]]s at rank 1.  The [[felid]] mutation is technically separate but equivalent to rank 1. [[Octopode]]s cannot gain claws (as they have no hands).

===Horns===
Grants an [[auxiliary attack|auxiliary]] Unarmed Combat headbutt attack. Damage rises with rank. At any rank, [[helmet]]s are prohibited; at rank 3, all headgear is prohibited. [[Minotaur]]s start at rank 2. Transmuters that are not wearing helmets may temporarily give themselves Horns 2 with Beastly Appendage. This mutation is mutually exclusive with [[Antennae]]. [[Octopode]]s cannot gain horns (as they have no skulls).
{{flavour|1. You have a pair of small horns on your head.<br>2. You have a pair of horns on your head.<br>3. You have a pair of large horns on your head.}}

===Antennae===
Lets you detect any monsters within a certain radius of you, even if invisible or through walls - usefully, this includes [[mimic]]s. Any rank prohibits use of [[helmet]]s, and rank 3 prohibits use of any headgear. This mutation is mutually exclusive with [[Horns]].<br>Rank 1: 3 tile radius (including the player).

===Talons===
Grants an [[auxiliary attack|auxiliary]] [[Unarmed Combat]] kick attack. Damage rises with rank. Wearing [[boots]] negates the effects of this mutation; at rank 3, boots are prohibited.

===Breathe Flames===
Lets you exhale a blast of flame as an ability. [[Dragon Form]] will temporarily give non-draconian characters Breathe Flames 3 (draconians will instead retain their natural [[breath weapon]]).

Gives you further mutations over time. Whenever it triggers, there is a 50/50 chance of you receiving either a good mutation or a random mutation (which means you are 3× more likely to receive good mutations than bad).

{{flavour|1. Your muscles are flexible, but weak.<br>2. Your muscles are very flexible, but weak.<br>3. Your muscles are extremely flexible, but weak.}}

=Scales=
[[Draconian]] scales function differently from those below: their AC increases as they level, and they may gain other resistances besides their scales. As such, they cannot develop any of these mutations. As they grow, [[Demonspawn]] naturally receive three ranks of a single scales mutation unless they are a "monstrous" demonspawn. They may still gain scales through other means of mutation, but they can only gain scales that they would eventually get on their own.

No character can have more than three total ranks of scales-type mutations at a time (e.g. if you already have Molten Scales 2, you could develop Large Bony Plates 1, but not Large Bony Plates 2). A [[Naga]]'s serpentine lower half counts as one rank of a seperate scales mutation, so they can only have up to two ranks of other types of scales at a time.

===Molten Scales===
