The DC to escape ropes is equal to 20 + the CMB of the creature that tied the bonds. Ropes do not need to make a check every round to maintain the pin. If the DC to escape is higher than 20 + the tying creatures CMB, the tied up creature cannot escape from the bonds, even with a natural 20 on the check. This rope has 2 hit points and can be burst with a DC 23 Strength check.
