You can get Black Desert Online for free, but only if you can reach level 56 in one week

Any players who can take a character to level 56 and complete the "awakening quest" before the 7-day trial expires will be given a free Starter's Package, which normally sell for $10/£8/€10. It doesn't include any "extra content," like a horse, Elion's Blessings, or House Furnishing Coupons, but it does provide permanent access to the game on either North American and European servers.
