Mana Optimization Strategy

How it works

By default, Sergei has Magic mana speed, requiring 5.5 tiles to charge. Equipping troops with a Mana Bonus can reach specific Breakpoints — the exact percentages where your tile count drops — allowing your hero to fire their special skill faster, with less tiles. Additionally, as a Druid, this hero can unlock a +4% Mana Bonus through Emblems (Talent Tree). These bonuses can significantly lower the troop level required to reach these breakpoints.
