It is not possible to break blocks within a 3x3 or 5x5 radius with any mod. The perks from the Apotheosis mod also don't work. Mining gadget breaks blocks on a 3x3 grid, but starts doing it from the lower left side and goes in turn, reaches the center, breaks the center and does not go further. An AoE spell from art nouveau also breaks only the lower left block of the 3x3 matrix
