Wisps are floating orbs of light that tend to orbit around Home Crystals and represent the amount of energy the player has. Once enough energy (hence, wisps) is collected by a player, they will be able to spawn a Bricktron.

There are three ways to generate wisps: 1- Over time, your Home Crystals will generate energy/wisps. 2- Capturing a Shard will cause it to generate wisps and send them to your Home Crystal. 3- When a Corruptron or Bricktron dies, the Wisp that lives inside of them will be released and head towards the player's Home Crystal.
