Things are getting very golden here in patch 11.1.7! With the recent addition of Overcharged Delves, it seems the amount of 
Gilded Undermine Crests has also been very much overcharged. So, how can you get to 75 of the best Crests that quickly? Let’s take a look.
30 Crests by Default
As initially spotted by minimaxir and Kainie85 it seems the crest rewards from Overcharged Delves are a lot higher than regular ones. Instead of the usual 7 Gilded Crests from Bountiful ones, players receive 10 from Overcharged Delves. The maximum you can get is also higher, capping at 30. So if you run only three Delves, you can get to the weekly limit. With how fast some of the Delves are, you could finish those three very quickly. We’ve even seen players getting all three done in 15 minutes solo. But we went with 30 minutes to leave you some breathing room, and in case your gear isn’t great.
30 More From The Map
The rest is pretty simple, and can be done in those same three Delves you run for the base Crests above. You’ll need a bit of luck or a bit of Undercoin for the next 30, as the 
Delver’s Bounty map has also been upgraded! It will still only give you 20 if you don’t run an Overcharged Delve, however, so don’t waste it. If you didn’t get a drop during your regular runs, you can always buy a 
Wave Scrambler 2000 for 2000 Undercoins if you have them, which will get you the map from the Undepin spawn.
15++ From Runed
The final 15 could be the hardest for you, and you can get them from upgrading Runed Crests. However, you will need to have the achievement to unlock the ability to upgrade. The 
Runed of the Undermine achievement requires you to have an item level of 662 in every slot. You will get 60 Runed Crests from the regular chests in the three Overcharged Delves you run, and another 15 from the Nemesis chests. Once converted, that comes out to 15 Gilded Crests. And if you factor in the weekly Overcharged Delve quest, you get another 12 Runed on top! This is also where you can basically get infinite Gilded Crests, since Runed Crests are now uncapped. You’ll have to run a whole lot more than three Delves, however!
So head on in and grab at least three runs a week for some big upgrade material gains!
