A block you can’t swing on but can ONLY be broken if a grapple hits it. Grapple would interact in the same way as if you shot stone, but the block would break. This could lead to levels being created where you have to break these blocks mid swing to maintain momentum, and generally more variety with swinging. (Although it is sort of a dumb idea, I think it would be a fun addition to the game.)

This is very similar to the other suggestions with breaking grapple blocks, but I think this one has more utility

So you would swing on it then it would crack then it could be broken

No. What I was trying to say is that you can’t swing on it, but shooting it with a grapple would cause it to break
