In the rule “Shamblers”, after the sentence ending “where x, y and z are numbers, referring to the number of Skeletons, Zombies and Ghouls in that Necromancer’s Cohort, respectively”, add:

The Attack Power of a Cohort is the sum of y and z. The Defense of a Cohort is the sum of x and z. If a Necromancer’s Cohort’s Attack Power is greater than the Defense of an other Necromancer’s Cohort, the former Necromancer is considered to be Stronger than the latter Necromancer and the latter Necromancer is considered to be Weaker than the former Necromancer.
Each Necromancer is either Stunned or not Stunned, defaulting to not Stunned.

Add the following new step as the first step of the Sands of the Hourglass action:

*For each Necromancer who is Weaker than any other Necromancer whose Location is set to same value (other than Tower), make the Weaker Necromancer Stunned. Stunned Necromancers are ignored when performing Hourglass Actions.

Add the following new step right after the step “For each Necromancer, perform any Hourglass Action described in the Effects of their Location to that Necromancer.” in the Sands of the Hourglass action:

*Make all Necromancers not Stunned
