Question about Berserk

Howdy, My friend got me into reading the Berserk deluxe hardcover books lately. I’m about halfway through the 2nd volume so far, and I already know that there are currently 14 volumes. My friend informed me that due to the author passing away back in 21, that it was finished by one of his helpers. I was curious if the hardcovers contained the final volume for berserk or if it ends off? I’m planning on buying them all but I don’t want to be left on any cliff hangers.
