This is a personal project to test out several effects I wanted to try out.
The beginning has the sword within the text as the center piece, but my favorite part is actually the flame animation on the top right and lower left corners. Those are shape layers with one straight line path, but with a large stroke width, a large taper, stroke waves, and a mix of wave warp and mesh warp. The CC Radial ScaleWipe was used to push the flames when the center circle expands.
The final shot uses expressions to randomize the placement of the flowing lines coming from the sword impact, and using a color picker on a gradient layer to pick the color of each line.
Between the first and second shot, I used impact frames to further sell the impact.
