Drow

**In-game description:**
*"The Drows believe that any crime can go unpunished if nobody notices you did it. They value and praise perfect executions, and will reward those who plan accordingly."*
## The Drow Faction

**Drow** were implemented during the Underworld expansion (v1.2). It is the Evil Prestige Faction, and will only appear when playing an Evil Vanilla faction. The Drow player will be able to combine the 2 faction spells and all the 18 upgrades and from both the Evil Vanilla and Drow factions. Several of their upgrades rely on Royal Exchanges and it is suggested to combine with the faction-coin-heavy Goblin Faction (forming something popularly referred to as "Droblins").

To Unlock Prestige Research:

1. Uncover the *Earth Core* Artifact with any Faction, and gather enough gems to be able to buy the Secrets of the Underworld (100 QiSxg (1E200) coins and 10 M (1E7) FCs)
2. When ready, play a Vanilla faction (Good Faction for Dwarf, Evil for Drow). Choose one that will be able to afford the Secrets of the Underworld. Do not buy the Vanilla faction's Unique building upgrade until you have bought the prestige Trade Treaty.
3. Once affiliated with the prestige faction, buy their Unique building quest, Unique Building upgrade, and then the Secrets of the Underworld. With the latter, the research button and prestige research will show up.

After you have unlocked Prestige research, the Vanilla unique building and Vanilla researches can be acquired before purchasing the prestige trade treaty. Plan in advance to not use up all your RUS on Vanilla researches, as prestige researches only show up after you affiliate with a prestige faction.
