A recent tweet from a credible Genshin Impact leaker revealed a new item that will allow players to convert talent ascension materials dropped by the three boss fights in the game.
Grinding the right materials for a specific character is probably the hardest thing in Genshin Impact, especially in after Adventure Rank 40 and above. You will most likely spend dozens of Resin before you get the right artifacts with the appropriate main stats and sub-stats.
Talents play a crucial part in any character's impact on the game. Even if you have a maxed-out character level vise, the perfect artifacts and weapon, your damage would still be lackluster if your talents aren't leveled up. For example, Diluc's Normal Attack at level 15 approximately triples his damage compared to talent level 1.
This being said, it is much harder to farm for talent ascension materials for levels six and above since they acquire special items compared to the lower levels. Those items are also called "Boss materials" because you can farm them through the weekly boss instances - Stormterror, Tartaglia and Andrius.
The biggest problem with this weekly system that it can take weeks or even months before you get the right materials. There are currently nine different boss materials and each of the boss instances can drop three different items. Many players were complaining about this problem and miHoYo finally decided to make some changes to this system.
According to Honey Impact, miHoYo will introduce a new item called Dream Solvent which will have the ability to convert one of the items into another, within the same instance. For example, you will be able to change Dvalin's Plume into Dvalin's Claw and Dvalin's Sigh. This will potentially shorten your time farming the right amount of specific boss materials by a staggering 67 per cent.
This isn't the first time miHoYo tried to meet the demands of a majority of the player base. They've already made similar changes to Character Primary Ascension Material by introducing the item Dust of Azoth which works the same way as Dream Solvent.
