Barriers are colored walls that will block the player's path unless the player has a certain Demon Blade--a special storyline blade received from defeating a boss.
In order to advance to the end of the current act, the player must beat the boss of that act and receive the Demon Blade they hold. Each new Demon Blade will allow the player break a new barrier type.
The player is not required to have the specific Demon Blade equipped to break the barrier, they just have to carry it in their inventory.
The order of the barriers players can break are: Red, Orange, Yellow, Green, Light Blue, Blue, Purple, and White.
- ↑ You will need to beat both characters' storylines in order to break white barriers.
