Some of the Chosens' possible weaknesses make them take additional damage from particular damage sources. These are:
- Shell-shocked - additional damage from explosives.
- Brittle - additional damage from close range attacks.
- Bewildered - additional damage when attacked 3+ times in a single turn.
How is this 'additional damage' calculated? Is it proportional to the damage of the attack in question, or is it a static bonus?
