As discussed with the GM, i should made a feedback threat in the forum:

--------------------------------------------------

Greetings Adventurer,
My name is Lead GM Chiro and I will be happily assisting you today.

I understand that you are reaching out to us, as you are wondering if there is any additional use for Cron Stones since they were given out during our events. Overall you are correct, upon reaching PEN you won't be able to use them for enhancements on your current gear anymore.

Nonetheless, as the game is always trying to add new things and classes, there will be opportunities in the future to use these stones. 

We highly encourage you to "Start a New Topic" in the [Forums > General Discussion > Feedback] section of our Forums to make your voice heard! Some other Adventurers may share your ideas and ▲like your post or add comments in order to increase its popularity! However, in order to facilitate communication between players, we kindly ask you to create your post in English!

Also keep an eye on the Adventurer Feedback Board. This is where the Black Desert Team will share updates from the developers to the player's suggestions!

Thank you again for your feedback, and we wish you all the best in your adventures.

Kind regards,
Lead GM Chiro
The Black Desert Support Team

As the GM and me realised, there is currently a problem in BDO. The Heidel and Calpheon Ball showering people with cron stones, but there is no point in using them specialy, now when everyone get the Dreamhorse for free. It's literally a DEAD item, you cannot even sell them to NPC for silver or do anything with them.

So i suggest to add atleast ONE of the following options:

- Add an Exchange NPC where you can trade like 3 Crons for 1 Caphra Stone

- Make Cron Stones sellable in marketplace similar as Memory Fragments and Caphras (Price could be between 0.5million and 2 million)

- Allow Cron Stones be sellable at NPC for Silver

Also the same problem applies to loot-scrolls, some people have over 10.000 lootscrolls and still getting more and more each day.. They cannot even use them that fast... So add an option to sell loot scrolls in the marketplace (Price could be between 20 and 200 million)

I'm assuming you are full PEN BiS Accesories, Slumbering God Armour & Blackstar weapons then? You can use crons for all of those items. A loooooooot of crons. 

I cant tell if this is a troll post or not.

if it doesnt affect you, it can still be good for other people you know? There is Zero Downsite to add more content/purposes for an item to the game.

You said it is a dead item and there is no point to use them??

I think the above post is right, this is just a troll post.

i quoted the official GM responce.. the point is if you are full pen there is no point in crons anymore.. this doesnt mean i have to be full pen.. this is a general statement.. thats why the suggestion is for.  There alot of people having full pen gear, also every single lifeskiller, who has no purpose for crons too.

Anyway, GM told me to post it in forums, i did it. doesnt matter if you like it or not. the issue still remains.

So I asked if you have full pen and you got omega defensive. I am asuming you do not. I don't think anyone has PEN Slumbering God in NA/EU yet? I also did not say I did not like the idea anywhere in my posts. Please point out where I said this? 

 "It's literally a DEAD item, you cannot even sell them to NPC for silver or do anything with them."

Still items to cron = not a dead item :)

If you had posted the suggestion alone without the falsities attached to it, maybe this would have been taken seriously.

The GM said this in the quote you posted:  "Nonetheless, as the game is always trying to add new things and classes, there will be opportunities in the future to use these stones."

So the GM already addressed your concern that there needs to be more uses for Crons.

That being said, maybe you aren't thinking outside of the box.  I can already think of a handful of real uses for Crons and I'm full PEN everything.  Even putting myself in the shoes of someone who's 765+ gearscore, I can think of a few ways they can squeeze out a use for Crons to progress their account.  I mean, look at Biohack.  Dude pretty much has every, single thing in the game, except for PEN Fallen God.  And he is probably one of the most heavy Cron users in the game.  He's an extreme example, but I juts hope you get the point here.  (You need use brain to find good use)

you are trolling mate

the game requires too many if anything. the need for them never ends as you progress, if anything you need more and more for each next ugprade

im convinced there is not a single person that has no use for them -  i dont know if there is a person with 2 pen fallen gods let alone all 4

lifeskillers exist? Not everyone aiming to get fallengod... Stop forcing people to play the game the same way as you do... Other people want to enjoy the game too.
