End crystal fire can be used to break all blocks in the end

End crystal fire can be used to break any block including bedrock (except for gateway and end portals - the crystal goes through the portal) if I block is available for the fire to generate on. The end crystals can only be pushed over immovable blocks from the north and west using the method shown. If blocks are pushed into the fire they are broken immediately and do not drop (tested with netherite block to prevent burning in fire). This can be combined with withers destroying gateway portals to create a stable wither cage.
