By accessible, I mean not taking 2 hearts a second just as standing on Bedrock would do to you. Here is the spot in question: Standing anywhere along that stretch of dirt/stone/grass will damage you - zombie or human. It is not an overpowered spot Zombies can easily hit you off from the side, or jump inside you. Any player can get there A simple backward jump will suffice. It has been like that since the start of Infection Proving that this spot has not been a problem, ever.
