What is the expected behaviour/value?

The Rattling Bellow notable modifier "Exerted Attacks have 8% chance to deal Double Damage" should have some impact on DPS for buildings that use warcries that exert attacks

What is the actual behaviour/value?

The "Exerted Attacks have 8% chance to deal Double Damage" mod is blue but has no impact on DPS.
The mod does get parsed to "ExertDoubleDamageChance" but then we don't ever do anything with it in CalcOffence

How to reproduce the issue

Equip melee attack, any offensive warcry, and a Megalomaniac with Rattling Bellow
Optional: Equip Brass Dome so strength doesn't impact damage
Allocate Rattling Bellow and notice that nothing changes despite you having exerted attacks and the mod being blue

No response

Start in CalcOffence, where the parsed ExertDoubleDamageChance modifier is currently not used. Reproduce the issue with a melee attack, an offensive warcry, and Rattling Bellow using the linked build code, then verify that exerted-attack DPS reflects the 8% chance to deal double damage.
