Basic Stats: Each hero has a series of stats which can be enhanced by fundamental game functions like Evolution, Skills, Divinity, Training, Gears, Building, etc. These functions have impacts on the stats and make the heroes stronger and safer in fights.
Every hero has 3 initial skills. Whenever a hero gets to the next higher level, he/she will receive a certain amount of Skill Points which are used to unlock new skills, either active or passive, and upgrade obtained skills. When other active skills apart from the 3 initial ones are acquired, you can choose the best 3 skills for heroes to use in battles according to different situations.
In every fight, there can be up to 3 heroes in the squad. Pick the best and the most suitable ones to fight for you. Sometimes certain combos of heroes have extraordinary impacts on the battles.
