Nope. I just remembered being asked a few months ago on the EU forums with regards to using the challenge cache’s gold as part of contributing to the 50 million gold streak conquest and I took a screenshot of it at the time to show that the gold value had been increased. I dug through my screenshots folder to find it.
[ EDIT ]
Here it is…

Much more sense now - I would Never have figured that out. Remember I am still new to D3. Even though in My Mind, I have achieved greatness with my monk. I played with 2 other friends who never quite got the hang of it. But they are casual players - I like a challenge and so hit the forums for what I could not figure out. You guys are great for being patient with me. If someone has never done a thing before - its hard to understand directions that are not given and just figured. It’s like being blind, and trying to listen to someone describing that color.
Anyways, if I am randomly playing someone else’s toon - How can I achieve a goal if I don’t know how to play it?
Is it possible to scroll thru a list of other ppl’s toons to one I know how to play? Or am I stuck with what comes up…
If you haven’t done it already, you might want to run this week’s Challenge Rift, so you have a better idea what to expect.
There has been no official word on it yet, but if Season 17 ends this Sunday, August 18th, there’s a good chance that Season 18 will begin Friday, August 23rd.
When the new Challenge Rift is deployed on Monday, August 19th, you’ll want to wait until Friday, after Season 18 starts to run next week’s Challenge Rift. 
And don’t forget:
Now, you can train all 3 Artisans to Level 12 and proceed with your Season 18 Journey. 
You play the Rift and build you are given. It will not change for the entire week. Figuring it out and completing within the time of the original run is why it is a challenge Rift.
Every week there are a few you tube vids on the CR. It will go over the map with Ellie and Champion placements do you can take the most efficient route. They also go over skills, and skill rotation.
I usually pick up a vid in my Reddit feed, but you can just search you tube. There is a different CR per region each week, so if you are on NA, search for NA challenge Rift. (vise versa for EU).
Some are easy enough to just jump in and play, but most are done with incomplete builds, this creating is own difficulties. (These are not impossible, as you are trying to beat some one else’s completion time. )
storytime42 already answered this for you. But, also keep this in mind: When you first enter the Challenge Rift you’ll be in the Challenge Hub. There, you can practice playing with the build to get a little comfortable with it. The monsters in the Hub don’t fight back. On the left side is a single large monster that respawns when you kill it. On your right side is a group of trash monsters that will respawn when you kill them. (Go back and watch the videos again. )
And, you can run the Challenge Rift as many times as you like. That is, if you do not successfully complete it the first time, you can try again.
Of course, once you successfully complete it, there’s no reason to run it again since you can only collect one CRift Cache per week.
just out of curiousity, how would u term the challenge rift in terms of T1 etc levels?
You should really just try the challenge rift in order to understand them. They are not based on a standard difficulty level. Each challenge rift is an actual Greater Rift run by a player.
Just try it.
They vary. But, of the few that I’ve run, they’ve been around GR45 to GR52, the best I remember.
If you go back and watch the video I embedded for this week’s Challenge Rift, look at the mini-Map. It says “Rift Difficulty 49”. That is the Greater Rift Level. “49” would be the equivalent of T10.
For a complete list of Greater Rift Levels equivalent to Game Difficulties see this chart:
That’s probably the best advice.
It’s not Friday 
I’m looking forward to it.
I’m not sure what you mean by that. If you’re waiting until tomorrow, there’s no need to. The new Season doesn’t start tomorrow. Go ahead and do this week’s Challenge Rift. You’ve got until Monday at 2 PM Pacific Time. Then, it will change to next week’s Challenge Rift.
If the new Season starts a week from tomorrow, you DO NOT want to do NEXT WEEK’S Challenge Rift until after the Season starts on Friday, August 23, 2019. But, you can practice with this week’s Challenge Rift all you want.
And, if Season 18 does not start a week from tomorrow, you’ll have 2 Challenge Rifts (or more) to practice with. Not to mention all the extra stuff you’ll get for successfully completing them.
ok I thought u meant I could not even make a level 1 non-season toon until after a certain time on Friday… Then do the challenge Rift drawing whomsoever’s toon I get to play.
Well thanks for all the help - truly - but its in vain cause they gave me a crusader to do the CRift and I have no idea how to play it. So back to just enjoying my Monk and working to get that last fist weapon.
There is a new Challenge Rift every week. YOU DO NOT HAVE TO CREATE A NEW LEVEL 1 CHARACTER TO RUN THE CHALLENGE RIFT. And you can run the Challenge Rift any day of the week.
THE ONLY TIME YOU WANT TO WAIT UNTIL FRIDAY IS DURING THE WEEK WHEN A NEW SEASON IS ABOUT TO START.
For example: Season 18 is starting next Friday, August 23, 2019 at 5:00 PM PDT. So, you WILL NOT want to run the new Challenge Rift, which will change on Monday, August 19, 2019, until AFTER the new Season starts.
When the new Season starts YOU WILL HAVE TO CREATE (OR REBIRTH) A CHARACTER. That Character will be Level 1. (But, it doesn’t HAVE TO BE. You could play your new Seasonal Character until they were Level “whatever” and THEN RUN THE CHALLENGE RIFT, if you wanted).
The point is, in order to collect the Challenge Rift Cache in the new Season, YOU MUST FIRST HAVE A SEASONAL CHARACTER that can collect it. And the point of running the Challenge Rift as soon as you create your new Seasonal Character is to start the new Season with a good boost to your currency, right out of the “starting gate”.
Yes. Every Challenge Rift will be a different Class and build. If you watch the current Challenge Rift videos, you can see how it is played. @Eazytarget puts one up every week. Usually within 24 hours after the new Challenge Rift starts. When you get into the Challenge Rift Hub, you can practice before your start.
Okay. Well, whatever you decide to do when the new Season starts, good luck and have fun!
@Shadowstryk
If you think you might want to do this week’s Challenge Rift after you create your Season 18 Character this Friday, August 23, 2019, here are 3 recent videos of it on the Americas Region:
And, if you decide not to run the Challenge Rift, then good luck and good hunting in your Season adventures! 
update: I have scarbringer w flawless royal; vengeful wind with same royal, 6 pieces sunwuko set - gems in amulet is bane of powerful rank 7 - rings - boon of horder rank 12, wreath of lightning rank 5. Paragon 260. bracer is an ancient legendary. Ok question I have is - is it possible to socket all gear? Other question is the legendary skills I have extracted, how do I add them to my gear or weapons. there is one thing on the cube that says reforge legendary - but I don’t see where I can choose a skill to add. Plus does it leave the rest of my weapon alone as far as not removing any skills? I am currently doing t7 bounties and the one to get keys. Going to try the greater rift today. I am also using 3 flawless royal for resists.
@Shadowstryk
You don’t. You equip the legendary powers just like you select your passive skills. Once you choose a legendary power, it will show up at the bottom of the Kanai cube, as well as in the detail section of your profile. Then you will have the advantage of whatever legendary powers you’ve chosen, regardless of what other items you’ve equipped.
One caveat: if you equip the same item as you’ve selected, you do not get double the effect. The equipped item overrides the cubed power. So, for example, you equip a Convention of Elements ring but also have it chosen as one of your cubed powers, the equipped item will override the cube. So if your equipped item only increases your elemental damage by 150%, then that is what you get and not the 200% from the cube.
tysm for your answers and directions… How many extracted skills can I add to my gear?
One from weapon/of hand
One from armor
One from jewelry.
And not really added to gear, but added to your character like a passive ability.
As TimberWolf and storytime42 stated, you DO NOT add “skills” to your gear. You “equip” the Legendary Powers using Kanai’s Cube.
Look at the image below. The left side of the image shows Kanai’s Cube opened. At the bottom you can see 3 Slots, already equipped. From left to right: Dawn is in the Weapon Slot, Visage of Gunes is in the Armor Slot and the Unity Ring is in the Jewelry Slot.
When you click on a Power Slot it opens Kanai’s Cube Powers Collection. (On the right side of Kanai’s Cube). This is where you select the Power you want for each Slot. You can only equip 1 Weapon Power, 1 Armor Power and 1 Jewelry Power at a time.
Once you’ve equipped your Powers, they stay with you, even in Campaign Mode. If you want to change your Powers, you can only do so in Adventure Mode. Kanai’s Cube is not available in Campaign Mode.
Use it with the cube recipe “Upgrade rare item”, rare item = yellow one
