Carbon Crystals? Base game vs DLC

[Hank Hill's Disappointed Sigh]

So a quick google search tells me there are plenty in the base game alone to upgrade all items but I am having some serious trouble finding them. I have the map locations roughly 80-85% complete, but have sort of come to a stand still.
My last like 10 hours of gameplay have been just running around doing question marks and outposts trying to find them and in all that time I found 2, both in random houses.
My braces and breastplate are all level 11 out of 14 but my staby hand and tool bag and quiver are all about 7 levels away from completionmeaning I need like 60+ more Carbon Crystals...

SO,
I am wondering if having the DLC's already installed has upped the cap on upgrades too? As in I probably won't find enough gems to get my gear to level 14 until I go to Sinai and the Valley of Kings. All the posts I've read say there are enough in the base game, but I am pretty sure they upped the max level for armor as well as character level.
Can someone confirm this before I drive myself mad? lol

I'm not sure how many are around in the base game, but I know there are plenty in the Curse of the Pharaohs DLC. Some areas there have potentially dozens of crystals.

Literally don't even bother worrying over it. You'll get enough of them by just playing.

You can find more than enough carbon crystals with out DLCs
You will need 50 alone, to open vault under sphinx

I buy them from Nomads Bazzaar, Reda, you know the geen camel.
He gives quests with rewards that you can sell.
Accumulate lots of furs animals weapons trinkets.
Sell off any weapons you dont need.
level 2 and 3 garrisons have them. Like a jewel box.
I'd lay in wait on the side of the road in Siwa for example send up Senu to check any incoming caravans and loot them for resources I can sell.
Killing guards and bandits gives tons of weapons.
Explore all tombs - pyramids.
Explore sunken treasure.
Use all this stuff to buy them if you can afford as they are quite expensive.
Upgrade the salesman abilitiy for Bayek, then goods sold for +25%.
You can also be gifted some gear, camels horses etc from doing side quests.
You can also buy better gear in Uplay Club rewards.
Also in the shop acces via AC menu.
As your level increases you get more XP and Dracmars I think is the currancy.
Use them in Ubisoft store.
