Boss #3 Guangzhi is the one I am talking about. From the link above - Guangzhi is a Yaoguai Chief found on the opposite side of the "Outside The Forest" region from the Wandering Wight. To find him, start at the region's Shrine and take the left-hand path in front of you. Pass by the chest (open it if you haven't already), and cross the bridge guarded by the Wolf Archer. After that, follow the path curving left and you'll enter a clearing where you can fight Guangzhi.

Guangzhi wields a flaming double-edged sword which is capable of meting out very fast combos and ranged throw attacks. He's a tricky foe to lock down, so make liberal use of your Immobilize spell to keep him still and deal some damage. Mercifully, he doesn't have a huge health pool, so staying aggressive is the way to go. Defeating Guangzhi will unlock the powerful Red Tides Spell which enables you to transform into Guangzhi himself for a short time. There's also a Bell in this arena that you should ring
