Lukou is a troll loa only mentioned in Shadow Hunter Ty'jin's ability called Blessing of Lukou. It grants a chance to recover vitality of an expired troop, and uses a healing spell icon, referencing Lukou's RPG information described below.
In the RPG
Lukou is the Loa of healing and respite, and she grants the ability to heal allies. With a word, the shadow hunter invokes healing with a wave of soothing light or can invoke a scintillating rain of positive energy, which drops from the sky to heal all living allies it touches. Her power has no effect against undead in the area- Lukou grants the capacity to heal, but she has no power over the restless dead.
