I saw some similar posts and people replying it’s not a bug, the reason I’m still reporting thinking it’s a bug because identifying what objects will make your Shurikens disappear is extremely inconsistent. One wall clips your shurikens, the other one doesn’t, some rocks do, other don’t, same for goes for different ladders, barrels, columns, trees, torches. Not to mention there’re some echo layouts like Lost Catacombs with lots of narrow doorways that also clip Shurikens (4th screenshot from the top, notice by the minimap these doorways are quite common), making it literally impossible to pass them without losing Blade Shield.
That inconsistency combined with the absence of the active shuriken number icon in UI or a clear effect indication whenever it gets clipped creates a very annoying uncertainty feeling with Blade Shield playstyle, makes me to second guess whenever I accidentally touched an “illegal object” and overcast the ability more than necessary “just in case”.
some examples of objects that clip:
