When i open a hero info, on the down left and right have two skill and talent, Can someone explain to me what function for this. Tq
A skill is an ability that a Hero has. When you deploy them you'll notice that they have both a green and pink bar above them. The green indicates your HP while the pink indicates your skill. Once the pink bar is full you'll set off whatever skill that Hero has.
As for a talent, this is a permanent feature to your Hero. The description tends to be accurate so it does what it says on the tin. Increase attack speed by 10%, yup it increases the rate at which you attack by 10%. Some are permanent, such as attack speed, while others have a requirement (such as damage enemies upon death).
Hope that helps.
