Guild Wars 2

I’ve noticed that bloodlust will stack if I go into reaper shroud while using the weapon with the sigil, would that also mean that I would gain the damage boost of Unholy Fervor if I shroud while using my axe?

Unfortunately not. Unholy Fervor specifically applies to axe skills. Reaper’s Shroud is similar to Engineer kits, where it will use the sigils of your weapon set, but is otherwise a separate weapon.

Crap, thanks for clearing that up though.
