I am currently running an Oriental Adventures (OA) campaign called The Divine Heir and the Jade Regent loosely based around the Pathfinder Adventure Path the Jade Regent with strong influences from Sekiro. The first adventure is called The Ashina Legacy and is essentially The Brinewall Legacy set in and completely converted to an OA setting.
I had to rewrite the adventure intro and re-theme the monsters but it worked well. Here is the flowchart of the adventure (and campaign).
Straight up conversion of the Pathfinder/3.5e version. My PCs encountered it then closed the door on it and just didn’t deal with it.

False Appearance. While the creeper remains motionless, it is indistinguishable from an ordinary flowering vine.
Regeneration. The creeper regains 10 hit points at the start of its turn. If the creeper takes fire, necrotic, or radiant damage, this trait doesn’t function at the start of its next turn. The creeper dies only if it starts its turn with 0 hit points and doesn’t regenerate.
ACTIONS
Acid Pellet. Range Weapon Attack: +3 to hit, range 10/20 ft., one creature.
Hit: 13 (3d8) acid damage. Any creature that takes damage from this attack must make a DC 12 Constitution saving throw or become poisoned for 1 hour. If the target is a humanoid that drops to 0 hit points as a result of this damage while poisoned, it dies as the spores takeover the body. Unless the spores are destroyed, a new phycomid grows after being dead for 24 hours. The bulb is destroyed if the creature is raised from the dead before it the phycomid can grow, or if the corpse is targeted by a remove curse spell or similar magic before it animates.
DESCRIPTION
This tangle of purple-capped mushrooms growing out of a nasty green sludge shudders and writhes, wafting tendrils of smoke
