In the video game Vampire Survivors, the best port build is a character build that focuses on increasing the player’s power through the use of the “Port” weapon and its evolutions.
The Port weapon is a powerful area-of-effect weapon that fires a spread of projectiles in a wide arc. When evolved, the Port weapon gains additional projectiles and increased damage. The best port build takes advantage of this by increasing the player’s projectile count, area of effect, and damage output.
