Better Happy Ghast & Dried Ghast

Deep in the Soul Sand Valley, a new structure awaits you: the Soul Altar.

Defeat the ghast and redeem your rewards!

After defeating the trial spawner, it may eject a Ghast Key.

Use the Ghast Key on the vault below to get your hands on the new Happy Ghast Upgrades.

Make your Happy Ghast faster, stronger, or both!

You can also drink an ominous bottle before entering to experience a harder version of the trial.

Happy Ghast Upgrades are used to craft better harnesses.

They can be duplicated with 7 diamonds and a bone block.

Additionally, you can replace the glass in the crafting recipes with tinted glass to get a cooler version of them: Sun Harnesses.
