Hey,

I'm currently experiencing a problem with Avarita's Skullfire Sword.
When I killed Wither Skeletons using the Skullfire Sword, they did not have a 100% Wither Skull Drop (~10% Roughly for me)

Could you kindly take a look at the mods and tell me if any of these mods might have caused this issue?

After doing some testing, I have confirmed that this is not an Avarita-Side issue, but rather some other mod is causing this.

Thanks!

• Wealthyturtle

It's definitely some other mod's fault, but I have no idea which one.

Alright then. Thanks

I have identified the incompatible mod as Iguanas Tinker Tweaks. I do not know what to do with this knowledge but put it here.

Thanks for catching that, TrypChangeling.

I use iguana tinker tweaks & avaritia together in my modpack and haven't had any issues with the skullfire sword, I think you might be using a mod that replaces vanilla skeletons with their own version.

The issue occurs with only Avarita, Mantle, TConstruct, and IguanaTinkerTweaks installed.

However, I've just figured out it's Iguana's MobHeads module, which is overriding all of the mob head drops, and seems to be enabled in both modpacks I've used with both mods.

In Iguana's Modules.cfg, the following clears it up:
B:MobHeads=false

Ah okay, I had that turned off already.
