Mummy Head + Unlock Mastery

[Tyronom]

Where do I find the mummy head? Finished map 2, never seen it.

Also do I need to collect all items in game and get all achievements to get the purple mastery?

the mummy head is around 230m if you look up and yes you need everything in purple for mastery

Thanks!
