Offhand

Offhand is a term used in game to refer to any limb with a melee weapon that is not the * primary limb. Certain limbs default to a default melee weapon if not equipped with anything, such as hands defaulting to fists. On game start, this defaults to either the left or right hand. Which limb is the primary limb can be set by moving the cursor over the limb on the equipment screen and pressing [Tab].

Classifications of limbs

The table below is to aid in describing what is considered an off-hand and what is not:

Limb type	Description	Base chance of attacking per turn	Affected by Offhand Strikes, Ambidexterity, Two-weapon Fighting	Jab eligible1	Flurry eligible
Primary limb	Main limb used to attack. Can be selected on the equipment screen.	100%	not applicable	not applicable	not applicable
Mutated Limbs	Limbs and weapons gained from the mutations: Multiple Arms, Burrowing Claws, or Horns2. Despite the name, it does not count limbs grown from being a Chimera, which are offhands.	Multiple Arms: (7 + mut Level × 3)% Burrowing Claws: 20% Horns: 20%	no	yes	yes
Robotic Arms	Arms granted by helping hands.	8%	no	no	yes
Offhand	Every other limb that does not fall into the above categories. See the below section for more specifications.	15%	yes	yes	yes

1. This assumes that the limb is wielding a short blade
2. Beak would fall under this as well but its peck attack is non functional as of 2.0.201.67

Additional methods of gaining offhands

Despite being called "offhands" any limb that can hold a melee weapon.

• If the left or right hand no longer is a primary hand, it becomes an offhand.
• Extra hands (and hand variants) grown from Chimera.
• Armor or modifications that can attack can make unconventional body parts count as off-hands: VISAGE, folded carbide wristblade, and any magnetized melee weapon will make the floating nearby slot an offhand.

All of these follow the same rules as normal offhands, which means they have a base 15% of attacking, can be affected by Dual Wield passives, Jab, and Flurry.
