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

Inizia in CalcOffence, dove il modificatore analizzato ExertDoubleDamageChance attualmente non viene utilizzato. Riproduci il problema con un attacco in mischia, un grido di guerra offensivo e Rattling Bellow usando il codice della build collegato, quindi verifica che il DPS dell’attacco exerted rifletta l’8% di probabilità di infliggere danni doppi.
