Income Fast: Grades, Traits, Towers

How Grades, Traits, mutations, and Tower runs feed plot income without wasting Gems or rerolls.

1. Core loop: roll → place → upgrade Money/Luck → better dice → rarer units → more cash.
2. Grade (Gems) is a flat income multiplier on a unit. Public tables list D≈1.1x through Z+≈25x — pour Gems into one keeper, not many fillers.
3. Traits overwrite the previous trait. S-tier all-stat traits (Transcendent / Monarch / Shogun / Samurai) are rare; stop or bank when Samurai+ lands on a keeper.
4. Mutations (Silver, Gold, Emerald, Diamond, Ruby, Rainbow, Huge, Titanic, etc.) are baked at pull — open units before selling.
5. Towers farm Gems / Trait Rerolls / potions. Treat them as a side loop: farm plot → attempt Tower → dump rewards back into Money/Luck/Grade.
