Virtuoso

Description
All lights are disabled; The player and enemies have a small spotlight radius.

Effects
All environmental light sources are disabled, meaning that the map needs to be traversed "half blind". Note: This does NOT disable danger-related lights, such as bullets or fires.

This makes the game more difficult by forcing the player to throw himself in disfavorable positions to progress through the map.

Unlock Condition
Earn 4,444,444 (or more) total score in a single run.

This is easiest to achieve by simply putting as many relics the player has already unlocked, and proceed to go as far in a run as possible, while killing every enemy and opening every chest. Note: Getting hit removes a fraction of the total score, meaning that a hitless run is most optimal, but not required.

Trivia

 * If mixed with the Phantomical relic the player and enemies' lights will constantly flicker, making both relics magnitudes more difficult.
 * This relic's unlock condition is a reference to the League of Legends character Jhin, who is obsessed with the number 4.
 * This relic's quote is a possible reference to a World of Warcraft quest under the same name.
