- Equip FIEND SAWS and IRON GAUNTLETS before forest sparring. Choose to start sparring in Jade Dancer, Young Mistress's Guardian’s dialogue; after teleporting, you face both guards. From the sixth-floor bell ①, follow the same level for about 20 m to ②. Turn toward the locked door ③, about 43 m from the bell. You need CRIMSON FOREST SHA-CHI TOWER KEY ×1. The purple arrow marks a lift to the lower floors, not to the roof. After opening ③, follow the lower map to the stairs at A. Climb the first flight to landing B, turn toward the bottom left of the map and climb the second flight. At the top tread C, keep facing the way you climbed and walk about 2 m onto the boards at D. No jump is needed. At D, head toward the top of the map, then follow the boards to the right around to eave P. Drop outward onto board Q, about 1.1 m below. Follow the blue route around the outside of the tower; round the two bends and follow the rising walkway to platform E. Face the lion-head chain above. When the interaction prompt appears, use HUNTER'S CHAIN SICKLE to cross to F. From the landing, follow the platform uphill about 9 m to Tie Gui ④. Once on the roof, walk about 4 m across the platform from Tie Gui ④ to Yuu ⑤ and speak to her to spar.
- One ranged attack cannot be blocked. Move across its line of fire or dodge, then close from the side. The enemy has a guard-breaking move. Leave room to dodge when it winds up for a heavy hit.
- Dodge the red-flash grab: blocking is ineffective. When he closes in, watch for the red flash instead of holding block throughout.
- One combo ends with a delayed blue-flash strike. Keep watching after the earlier attacks and perfect-block the delayed hit just before impact. Do not attack during the pause.
- Defeat both guards in forest sparring, then finish the return dialogue to receive Heel Reinforcement Part ×1. In the village, FIST FRAGMENT: CORE is awarded after the hidden branch’s final phase and ending scene, not picked up immediately after this guard falls.
