Someone asked me if there is a maximum bonus percentage in the game for anything. From what I know, there is no maximum.
For example, if you want to make your traps as powerful as possible, you can:
The same is true for Troop Bonuses and Resource Bonuses.
Hero (as shown): Hero Bonuses are exactly as they appear. A 15% food Production Bonus means 15%.
Hero Skill Points are only applied to Troops/ Marches/ Rallies that your Hero is in. For example, if you put Skill Points in Gathering, you must have your Hero in the Gather March.
Research (stacked): Research Bonuses are stacked. Researching lvl 5 food Production means 1+2+3+4+5 = 15% total bonus. (Great news, right!?)
Buildings (cumulative): Villas are cumulative as in the more Villas you have, the more Training Bonus received (1% Training Speed per level of each Villa)
Something To Consider: Early in the game, I crafted all purple Construction and Research Gear. I could have waited for yellow, but I figured the time savings wasn’t worth the wait. Now, later in the game I am replacing my purple research items with yellow items since some of these Researches are so long and the extra little percent can equate to a few days or more. Everyone needs to keep this in mind when applying Hero points and especially when Crafting items."
Enjoy!
