Create a new rule “That Angry Scorpion” as a subrule of “Creatures”:

That Angry Scorpion’s stats are: Strength-1 Dexterity-15 Constitution-10. Its loot is a Poison Barb and a Potion of Strength. Its Health is 20.

When an Orc’s Health is decreased as a result of that Orc Attacking That Angry Scorpion, that Orc loses 1 Strength (to a minimum of zero).

Create a new rule “Poison Barb” as a subrule of “Items”:

Affect: When an Orc who holds a Poison Barb causes a Creature to lose Health, they may cease holding the Poison Barb to decrease that Creature’s Health by a further 10.
