Challenge rift 299

Hi All I have played D3 for a while now but never really done challenge rifts.
I need a challenge rift cache to upgrade the Alter.

Any one got any tips for doing it i’ve spent 4 hours both solo and in groups but can not complete this in time. I’ve watch some YT videos but they not helping at all.

Are they all this difficult or is this one exceptionally difficult?

Just so I can gauge if its even worth trying to advance the alter any further?

Thanks in advance

Its “Altar”.

I haven’t tried this one, but some setup are “wtf?” and some are easy. It’s not the first time the CR would be hard. Some time ago there was even so hard one, that Blizzard changed it.
