Each effect is a sprite sheet on a pure #00ff00 chroma-key background (flat solid green, no gradients, no shadows, no texture). The background will be removed programmatically. Do NOT use green anywhere in the effect itself.
All sprites should be in a cel-shaded / anime game style matching Soul Knight (魂斗神) and Survivor.io (生存争颋) aesthetics:
- Bold outlines, vibrant colors, clean shapes
- Slight transparency on outer edges for glow blending
- No realistic fire/water physics - stylized game art
