Each hero is given four different abilities that it can level up throughout the course of a game. Since each hero starts at level one it is up to each individual player to continue to level up and up grade it's abilities. At the beginning of a match you are given one point to upgrade one ability to start off with. You can choose between your Q,W,or E. Each hero has it's own unique abilities customized to it's type. Like carry's, they usually have an ability to stun a target or to single an individual player out. These abilities can give your team the upper hand when it comes to team fight or even just protect yourself from one on one encounters. The final fourth move you learn is called your ultimate move (ult) designated to your R key. You don't get this ability until you reach level six. These abilities are incredibly strong and can change the tide of a battle or even a match. Along with being so stong they also have a long cool down time which makes the timing of the ability that much more important. Unlike the other three you can only upgrade your ult three times throughout a match. At level six, eleven, and sixteen. With each upgrade comes even more power whcih makes them almost unstoppable. If you want to make them even more powerful you can build an item called aghameniem's spear which upgrades almost every heroes ult. When choosing a hero you need to keep the hero's abilities in mind. Make sure it's someone you know and are comfortable using for the entirety of a match.
