Managed to replicate this NX visual bug since I've always had one too :3 This is how the Shadow Style item effect look like: ---------- NOTE: Characters can be in either what I'll call in-combat mode (when you're attacking or taking damaged and/or your character "breathing," bobbing up and down), or out-of-combat/rest mode (when your character isn't damaged by any mob and/or standing still swaying back and forth). Here's a clip of the visual bug, with timestamp and explanations below (keep in mind that that the item is always toggled ON during the clip): ---------- With item toggled ON, the effect stays when moving from rest mode to in-combat mode (0:00 - 0:04), but: 1. The bug occurs when your character starts attacking after landing on the ground (whether from jumping or falling) and NOT having any directional keys input w/ the attacks. (0:05 - 0:11 & 0:26 - 0: 31) 2. The bug also happens when your character starts attacking after moving then stopping (move, stop, then attack), while NOT having any directional keys input w/ the attacks. (0:11 - 0:15) Interestingly enough, the effect still works if you hold directional key(s) while attacking after landing /stop moving (0:15 - 0:18 & 0:24), or attacking in mid-air (before landing). (0:18 - 0:23) ---------- Note that this visual bug seems to occur ONLY during your character's in-combat mode under the scenario above, and it can happen with any attack/skill animations of any classes.
