Dandpatta

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.

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.
