Brainwave is Faceless's faction spell that increases all buildings' production progressively over the duration of the spell. This spell can be enhanced just by extending its duration, which is possible through Druid Challenge 4 Reward and various Researches.
Because of its long duration, it is impractical to get many casts in the same game, as most runs will end under a few hours. For requirements that require getting spell cast counts, abdicating to reset all spells is a common strategy.
