Larian Studios Forums Divinity - Original Sin Divinity Original Sin - Help/Tips/Tricks Is the Immaculate trial worth the effort?

I lockpicked the door to Loic's secret area which takes you to Sacred Stone. I also have an amulet to gain entry.

Is there any reason to do the trial? Does it give a good XP boost or any good items? I seem many people complaining because of the difficulty.
