How to complete The Great Hollow event in Elden Ring Nightreign and break the crystal curse

So you're wondering why you've suddenly been reduced to 50% HP while trying to explore The Great Hollow map? Elden Ring Nightreign's new Shifting Earth event has a special (and somewhat annoying) mechanic called the 'crystal curse', which inflicts a half-health reduction whenever you enter the castles or ruins in each corner of the map.

This isn't ideal since those areas contain the best weapons and are the most lucrative when it comes to farming runes and gaining strength to face the new night bosses.
