1st at all, sorry for my bad english...
Right now, I’m reading the second book (after the firsts interludes) of Oathbringer, and looking for information about Szeth in Coppermind, I read that the sword that Szeth got on WoR, appears on the Warbreaker 4th story.
Do you recommend me read first this story before continuing OB? Or is not 100% necessary? Is is necessary, I can read the 4th story without read the rest book?
My intention is read all cosmere books, WB included.
Thanks!
EDIT: SPOILERS OB and maybe WB
