Grand Balance is Druid's spell that increases the lowest production building massively based on the three highest building counts. Due to Druid's faction upgrade "Mabinogion" scaling up the power of this spell based on how low the tier of the target is, targeting Farms can generate very high production.
Because its challenge upgrade enables increasing the production of every building, it is also a staple spell for many Mercenary Research builds, since it is viable to build up to 10e9 mana quickly through offline mana regeneration.
