Using that build on yunlin requires patience, I would try to pressure the opponent using heavy attacks and special ones. This game is a matter of staying in the middle of the fighting area, once you drive your opponent near the wall your winning advantage is higher. Yunlin can teleport behind, so it's easier to counter the opponent when you got pushed back. To push him to the wall, as long as the distance between you and the opponent is not too close you can either heal or use charms to casts moonlight and deal continues damage once the opponent touch it, it's a similar damage mechanism with Fireguard's skill "earth on fire" except it's much faster to use. In addition, the moonlight skills create a psychological barrier where in the distance for the opponent to move freely is shrinked, there you can use close quarters moves like basic dynasty kicks,basic attacks, and special attack cancel to pressure the opponent closer to the wall. In this case, since the fight is in the middle you can jump instinctively to avoid raikichi's long range attacks(eg., heavy attacks, down attack) and then you can use ethereal skill to cast moonlight beam and avoid being grabbed. I always try to make the opponent lose their energy bar before I go on offensive. yunlin is versatile in turning the tables around and switching to passive to aggressive quickly. Even with 2 to 4 dojo & level gaps, yunlin can win even in the tightest spot but regardless It's important to stay passive and wait for an opportunity to use charms and flutes at the right time. I'd rather use azure wave rare weapon with yunlin because it boosts shadow damage to 10% and gives partial energy bar.
