Hero Review

Ruby: The Nuclear Option in a Ninja Suit

"Remember when 100% mana cut was considered a war crime? Ruby does. She might not have the stats of the modern era, but her 'delete mana' button is timeless. We break down if this glass cannon can still fire before shattering."

How it works

By utilizing the Hero Coach, you can reach the Maximum Ascension of a Legendary hero instantly. This bypasses the requirement for rare 4★ Materials (like Alpha Aethers and Damaskus Blades) and ignores the traditional leveling time.

Mana Optimization Strategy

How it works

By default, Ruby has Ninja mana speed, requiring 4.9 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 Barbarian, this hero can unlock a +2% Mana Bonus through Emblems (Talent Tree). These bonuses can significantly lower the troop level required to reach these breakpoints.
