Ok, so SPOILER, SPOILER, SPOILER, don't read if you haven't finished the book.
Everyone was extremely sad with another loss to Bridge Four, and the way it happened, heart wrenching. I imagine though, killing spren is going to be far harder than the fuse think because.... shard blade/shard shields. Now that the Radiants know about this, their spren just need to make sure they manifest in their shard blade form if someone is trying to stab them. Thinking of that made me take a deep breath. Side note, can someone explain to me how this will allow conservation of investiture to be maintained?
