Where To Find Diluc's Ascension And Talent Materials
Where To Get Diluc's Required Gemstones
Agnidus Agate Slivers, Fragments, Chunks, and Gemstones can be received from the Pyro Regisvine Boss in Cuijue Stope. You can receive rewards from this boss by spending 40 Original Resin.
The Pyro Regisvine will also drop Everflame Seeds, which is currently the only way to get this material.
Where To Get Diluc's Required Common Drops And Books
Small Lamp Grass is a Mondstadt specialty flower that is usually found in shady areas. You can find large amounts of it in Whispering Woods and Stormterror's Lair. Additionally, you can use this farming guide to maximize your Small Lamp Grass gains.
Teachings, Guides, and Philosophies of Resistance are a reward from the Forsaken Rift Domain on Tuesday, Friday, and Sunday. They can also be gained in small amounts from time-limited events, and sometimes as a reward from opening chests.
Recruit's, Sergeant's, and Lieutenant's Insignias can be obtained from Fatui enemies. These enemies are relatively strong and can be found all around the map. Use the Traveler's Handbook to find specific locations where Fatui are hanging out.
How To Get Mora
In total, you will need roughly seven million Mora to fully upgrade Diluc. This is the total of cost of ascending, upgrading talents, and leveling to 90.
You can get Mora from most activities in the game, but we recommend using the Ley Line Outcrop: Blossom of Wealth for the most efficient method of gathering Mora. You will need to spend 20 Original Resin to receive rewards from Ley Line Outcrops.
Experience and Rare Items
To upgrade Diluc to level 90, you will need:
- 414 Hero's Wit
- 15 Adventurer's Experience
- 12 Wanderer's Advice
These numbers are a rough estimate and don't take into account experience gained from defeating monsters. Additionally, you can use any combination of experience books to reach level 90. Use the Ley Line Outcrop: Blossom of Revelation for the best time gathering experience books.
Dvalin's Plume drops from the weekly challenge Stormterror's Domain. This material only has a chance to drop, so be sure to challenge this domain every week for the best chance at getting one. The first three weekly bosses you challenge each week will only cost 30 Original Resin, instead of the usual 60.
Finally, you will need three Crown of Insight to fully upgrade Diluc's talents. These items are especially rare, and can only be obtained from time-limited events. These events usually occur once per version update, so check back frequently for a chance to get a Crown of Insight.
