Due to extensive training with whip class weapons, you have achieved mastery in using them on the battlefield. 

• Whip class weapons now have a damage dice of 1d6 instead of 1d4.
• Once per turn, as part of connecting an attack with a whip against a creature large or smaller, you can attempt to grapple the creature.
• When you use the Attack action and attack with a one handed weapon, you can use a bonus action to attack with a whip you are holding.
