Finding the splinter of darkness

[MaroonMaurader]

From the Info thread (DGDobrev), I quote:

Moro Dark (or Moron Dark, direct translation )
A former knight who sold his soul to the dark forces. Fighting evil, he's constantly striving to cleanse his soul.

Item slots: Weapon, Armor, Helm, Belt/Regalia
Found where: Elon
When dismissed: takes nothing, except for any items you've equipped on him
Innate traits: +3 Attack (Hero), +1 Morale to all undead
Abilities: Struggle with the Darkness; Training

- Struggle with the darkness
Mauron Dark has a special parameter, called "Power of Darkness". When he joins, it's at 100%. After each battle, it is modified by:
-5, if there are undead in the enemy army
-4, if there are demons in the enemy army
+2, if there are demons in your army
+1, if there are undead in your army
Each of these modifiers is standalone. So, for example, if there are both demons and undead in your and enemy army, the modifier will decrease by: -5-4+2+1=-6.

When the parameter reaches 0%, you will get a very special and powerful item "Shard of Darkness". When equipped, it improves the Attack of all Black Knights by 10 and grants them the "always retaliates" ability.

(End quote)

It always seemed a little weird to me that an item that benefits only black knights was ideally obtained by not having black knights (or other undead or demons) in your army...
