The following tool is for randomly generating gems for upgrades in your own Watchers in Death campaign.
Each model is limited to two gems per Weapon, two gems for Armour, two gems for Shields, and one Jewelery gem. Once a gem is equipped it cannot be removed without being destroyed.
...of Exploding (Weapon): After allocating all the wounds from this weapon, for every model slain roll a d6. On a 4+ that model's unit suffers 1 mortal wound.
...of Protection (Shield): Reroll failed saving throws of 1 and 2.
...of Mirroring (Armour): Roll a dice each time you allocate a mortal wound to the bearer. On a 5+ the wound is negated.
