Surviving Armageddon

[lch]

I spy into my little crystal glass and I see...

Armageddon kills 20% of the population in every province. Afterwards, all units on the map (not in special provinces like the Arena, the Void or the hells) have a 20% chance to fall victim to an attack. The attack is a single body hit, with 15 damage of type earth (which prolly means it's mundane damage). There's some spec value set, I don't know about them enough, but apart from what I already said, it's the same attack like the ballista and crossbow bolts when somebody visits an adventure site.

As far as I can see, there are certainly no special abilities that protect from the attack, nor are there any defense rolls.
