The multiple attack penalty you take with this weapon on the second attack on your turn is –4 instead of –5, and –8 instead of –10 on the third and subsequent attacks in the turn.

This weapon is designed to be inconspicuous or easily concealed. You gain a +2 circumstance bonus to Stealth checks and DCs to hide or conceal a weapon with this trait.

You can use your Dexterity modifier instead of your Strength modifier on attack rolls using this melee weapon. You still use your Strength modifier when calculating damage.

This weapon can be used defensively to block attacks. While wielding this weapon, if your proficiency with it is trained or better, you can spend a single action to position your weapon defensively, gaining a +1 circumstance bonus to AC until the start of your next turn.

These weapons are used as a pair, complementing each other. When you attack with a twin weapon, you add a circumstance bonus to the damage roll equal to the weapon’s number of damage dice if you have previously attacked with a different weapon of the same type this turn. The weapons must be of the same type to benefit from this trait, but they don’t need to have the same runes.
