If you still have the Sacrificial Heart after going to Cruel - Then this will help

I made a quick 2 min guide on how to get rid of that pesky heart in your inventory!

If you do not want to watch, the steps are:

1. Travel to Act 3 from Cruel
2. Go through the portal at the Ziggurat Encampment
3. Complete the Riverbank in Cruel and get to Riverbank Encampment
4. Waypoint to Act 3 from Riverbank Encampment - you should be able to see the Aggorat waypoint
5. Go to Aggorat and sacrifice the Heart!
