Horns

Horns is a mutation that grants the natural equipment on the character's head.

If the character has multiple heads, the horns will only be equipped onto one head. Like other armor, the AV and DV will be averaged across all heads. As well as being armor, Horns act as a short blade weapon type, and can benefit from the Short Blade skill and associated powers. They are one of the few short blade weapons that has an uncapped strength penetration modifier.

When the player selects the Horns mutation, they can also it by pressing "C" during character creation to select the variant of horns they would like. The options are: Horns, Horn, Antlers, or Casque. Mechanically, these variants are identical to each other.

The player can select their horn-bearing head as their primary weapon from the equipment screen in order to always attack with their horns as their default weapon. Otherwise, there is only a 20% chance to attack with the horns to when making an attack with any other primary weapon.

When a creature with Horns uses Charge, the chance to attack with horns will be 100% with the bonus penetration from charging. This chance is separate from the default 20% chance to attack with horns, allowing a charging creature to strike up to twice with their horns.

Bleeding effects inflicted by do not stack.

Formulas
The following formulas are used to determine damage and other effects based on mutation level.

Advantages

 * Grants essentially free extra damage.
 * Grants a very significant AV bonus compared to most head armor, particularly in the early game or if rapidly advanced to high levels.
 * Horns are weightless and have no DV penalty.
 * Very accurate even with low Agility due to their significant to-hit bonus.
 * At high levels, the significant bleeding save difficulty will cause creatures to bleed for many turns just from being hit one time.

Disadvantages

 * Prevents the player from wearing any headgear
 * Prevents the player from benefiting from any head mods, such as lanterned.
 * Horns do not grow back if the head they are on is decapitated and then regenerated, unlike
