Double-muscled

Double-muscled is a physical mutation that increases the player's Strength. Additionally, every melee attack a creature with Double-muscled makes that hits and successfully penetrates has a mutation level based chance to daze their target for 2-3 rounds. This effect functions similarly to dazing caused by a critical hit from a cudgel, and will stun creatures that are already dazed. A single attack can daze more than once if there is multiple sources of daze, such as a cudgel's critical hit or Bludgeon. This can stun a target with a single blow.

Formulas
The following formulas are used to calculate strength bonus and daze chance based on mutation level.

Advantages

 * Additional strength causes the player to do more damage in melee via additional penetrations, as well as increases carrying capacity
 * Gaining strength from a mutation rather than by increasing it through the Attribute Points granted at level-ups allows those points to go to other Attributes, or allows you to get extremely high strength
 * Synergizes well with weapons/mutations that have uncapped strength bonuses, such as Horns
 * Synergizes well with mutations that grant additional limbs that can be used in combat, such as Multiple Arms
 * The daze effect caused by this mutation can often prevent enemies from reacting to your attacks or fighting back. Dazing an already dazed creature will stun the target instead.

Disadvantages

 * Moderate cost at character creation
 * Grants a relatively low strength bonus at mutation level 1 and takes many levels for this bonus to significantly increase
