"The Elden Ringwall was set as a destructible object however, having 9999 HP with no animation fade out, suggests it was most likely designed to be destroyed by the event's script" Zullie explained Zullie via Twitter. "Though it's unclear if they threw that in Elden Ring Runes or if it's bugged. It must have 9999 defense though."Illusory Wall, another well-known Dark Souls expert who also believed that this fake wall wasn't intentional confirmed Zullie's findings and agreed with their theories regarding the wall.
However, as long as the developers FromSoftware and Bandai Namco officially clarify if this fake wall or other similar hard-to-break secrets are deliberate techniques or bugs that were not planned that we cannot say for certain. MMOexp has spoken for clarification to Bandai Namco about the fake wall, and whether it's an issue that could eventually be fixed through a larger update similar to the recently released 1.03 patch.
