question about unholy might and vulnerability curse?

how does unholy might and vulnerability curse interact with each other?
i am playing holy relic of conviction. unholy might is 100% phys to chaos damage
vulnerability curse is 15% more phys taken.

is it just 15% more damage?

thanks

The damage monsters taken is going be chaos damage. Vulnerability will do nothing with unholy might. Use despair instead.

i am running a trippel curse on hit setup with myself doing 2 (despair and vuln) and my animate gradian is doing enfeeble.

As comment above. When you have unholy might active, the enemy is taking chaos damage, so increased phys taken will not increase the chaos damage taken.
