Alchemy Lab.gif

The Alchemy Lab is an advanced crafting building that transmutes lower level items into higher rarity ones, other items of the same rarity, or transmutes farmable ascension materials into non-farmable ascension materials of the same rarity. The Lab can be converted after unlocking Stronghold level 23 from any non-storage building of level at least 5.  

It was released in June 2019 along with several other advanced buildings after first announcement in December 2018 and much anticipation (see the original Idea/Suggestion thread). Some original criticisms were improved in version 30 (June 2020).

However, the Alchemy Lab has several limitations that the other crafting buildings such as the Training Camp, Forge or even Hunter's Lodge do not have:

  • Level 10 requires Gems to use.
  • You can not speed up or skip Transmutation times with Gems.
  • You can choose which ingredients go into the cauldron but not the output results. For conversions to the same rarity, you can influence the output somewhat because it is guaranteed to not be the same as any of the ingredients.

Alkashards

The Alchemy Lab also introduces a new item called Alkashards. Alkashards are produced with every completed transmutation, the amount depending on the Level of the Alchemy Lab as well as what items are being transmuted (see table below). 1000 Alkashards can be combined into one of 6 selectable items.

When collecting the transmutation results, the produced Alkashards can be supplemented in exchange for gems (again, see below for ratios).

Rewards for combination of Alkashards:

  • Slot 1: 90%: 3 star ascension material, 10%: 4 star ascension material
  • Slot 2: 3 star ascension material
  • Slot 3-4: 30 emblems
  • Slot 5-6: 5 five star battle items

Statistics

Each level unlocks two recipes (marked X for transmutation on the same level and U for upgrade to higher rarity).

At higher building levels, several concurrent transmutations are allowed: Up to level 4 only 1 transmutation is allowed; between levels 5–9 you can run 2 parallel transmutations; on level 10 you can run 3.
