It's missable because if you don't pick it up before you go down to the room that explodes on you there is no way of getting back in that area to get it. I finished the game with 99% items and had to start a new game because I couldn't get back in that area. Not really that big of deal since you have to play the game multiple times anyways to get everything, just trying to let others know about it.
