If you are new to the game, take advantage of the heroes you get first (AKA Eudora, Zillong, Layla, and Miya). Once you get the hang of someone, choose someone that can be based on your needs. If you want to use your skills more than a basic attack with magic power (Mages), you can use Gord, Esmeralda, Alice, or Aurora. If you want to have a hero that slowly develops over time with offensive/defensive capabilities (Fighter), use Balmond, Bane, Badang, Sun, or Guinevere. If you want to be the backbone of your team (Tank), use Tigreal, Atlas, Gatokaca, or Franco. If you enjoy using your basic attack with an extended range (Marksman), use Granger, Lesley, or Claude. If you like helping others (Support), use Angela, Rafaela, or Diggie. If you rely on quick kills (Assassin), use Natalia, Helcurt, or Hanzo. The possibilities can be endless with your selections!
The one carrying the special needs is the siege/cannon minion (AKA the one with an arrow). During the timeframe, the mid-lane will also be adjusted. Instead of a Cannon/Siege Minion, an Infantry and three Lancer minions will spawn instead.
For example, use Guinevere’s 2nd skill as a way to suddenly surprise the enemies when ganking.
It’s better to not attack the Lord until you wipe out the enemy team or when the enemy is focused on a team fight (or defending the base) that doesn’t include you. This is so the enemy team avoids ganking for the last shot. Also, wait for the 12-minute mark. The Lord will be enhanced and will attack a turret that’s on the lane.
Remember, killing enemy heroes isn’t the objective, destroying the base turret is.
If you want to be stylish, buy skins for your heroes! Even though it only gives a small boost for your hero, it will impress your team! (Diamonds are needed to get skins, or via limited-time events that can give it for free or etc. )
