If  that's even possible, I'd like Hexer to receive the same treatment with its Dark Water. But so there are implications about how Light and Darkness field effects, thematically, discern no one from allies or foes. It sounds intentional? Yes. Is it fun/balanced? Nah.

Light Shards, Dark Water and Sanctuary all could be changed*, but standardized into "only affects enemies" accordingly.

*
Light Shard = Enemy: Reduces Hit by LV. Reduces the Momentum of Undead and Ghost enemies standing in it by 2. (Half-effective vs Possessed and Vampires)
Dark Water = Enemy: Reduces Status Resistance and Critical Evade by 30%. (Half-effective vs Boss monsters)
Sanctuary = Ally/Self: Reduces damage taken by 5%. Enemy: Tile effects cannot be placed down in the same tile as a Sanctuary.

Why the nerf to dark water tho
