I am using snares and when the white particle effects are on the hostile mob and I kill it, it does not drop and demonic wills. I am using BloodMagic-1.8.9-2.0.0-253-ss.

If you're using dev builds, that is 30 builds out of date.

Also to clarify this was in a multiplayer server in the unstable modpack. I tried it in single player and it worked

@TehNut I am going by what ftb is using for the unstable mod pack

They should definitely not be shipping that version anymore since an update was pushed since then... Are you sure you're on latest Unstable?

Yea it is still at that version. I am using Version 3.0.29 of unstable. Which is currently the most recent version of that mod pack.

Can confirm it's no longer happening with BloodMagic-1.8.9-2.0.0-18.
