Notes
- Ore Crystal Bug is Light + Earth dual-attribute, with high Physical Defense (102) but low Speed (52), Magic Attack slightly higher than Physical Attack (81 vs 77)
- The trait "Polarization" reduces damage taken from attacks matching its own skill types by 40%, so carrying Light/Earth-type skills provides both offensive and defensive benefits.
- Skill pool focuses on Earth-type Physical damage, with Light-type only having support and basic skills, lacking high-power Light-type output.
- Speed disadvantage is obvious, needs to rely on defensive moves or buff moves to create damage windows
- Diffuse Reflection can boost power of different typing skills, suitable for pairing with multi-typing offensive moves
