An "obstruct" happens when a projectile hits something unintended like an object or a part of the terrain while on its way to its target, which will make the the projectile disappear and momentarily replace it with the sign "obstructed". An "obstruct" may happen to most types of projectiles launched by any object or character.
- From time to time, projectiles might pass through some terrain or thin and small parts of the environment. It is unknown if this is an intended "penetration" feature or a simple glitch related to the geometry of the world and its surface collision.
- Sometimes, when using some skills, it may look like an "obstruction" happened, but the intended sign will not be shown.
