10. Irithyll Dungeon - Dark Souls III
The Dark Souls franchise and FromSoftware games in general are renowned for their densely-packed, tricksy level design, and this arguably never grates worse than it does in Dark Souls III's infamous Irithyll Dungeon.
Though not strictly the toughest Dark Souls area from a pure combat difficulty perspective, the dungeon is infuriating to navigate for even well-honed Souls players.
The confusing layout, combined with the brutal bonfire distance, and tendency for those damn jailers to get the drop on you, makes Irithyll Dungeon a stamina-draining slog of a level.
The sheer repetition of traversing the dungeon will test the patience of even the most ardent fans of gothic architecture and neo-romantic art styles, ensuring the mere utterance of the area's name will make most shudder if not groan.
