Edge of Shadow is perhaps your most important ability as a DK (and proper usage marks your mastery of the class), but I can't find a satisfactory VFX edit for this skill. It needs a more distinguished sound effect, hard-hitting feedback, and an edgier visual style more befitting of the class.
The Abyssal Edge adds a new crispy sound effect so you can easily check the usage of this skill during your 2-minutes burst window. It also replaces the ball-like visual effect with a lasting abyssal slit modded from Dark Force. A small camera-shaking effect is added to give heavier feedback, although it is not as strong as some of the most heavy-hitting skills in the game.
To use this mod, unzip the package and install the two ttmp2 files through textools.
This is my first time editing a VFX, so let me know if you have some suggestions/feedback regarding this edit (either through the comments in the youtube video or reach me in discord at Ted Cheng#8337).
