Blizzard's digital card game, "Hearthstone: Heroes of Warcraft", will be adding a new free hero card, Morgl the Murloc Oracle.

The game has added the character Khagdar last April as part of the Earth day promotion. After that, there is no additional hero card added. Just recently, however, Blizzard added a new card, Morgl the Murloc Oracle. This new card will be free of charge if the player introduces a friend into the game.

Murloc is a race of small fish-like creatures who are known for swarming in large numbers and making weird gurgling noises. They swarm the board while buffing each other giving only little time for the opponent to react.

The game, "Hearthstone: Heroes of Warcraft", is somewhat intimidating. There are lots of rules and cards to consider. This might be one reason why Blizzard gave away freebies for those who can add a friend to the game using the new 'Recruit a Friend' feature. This new card cannot be purchased and can only be acquired when the friend recruited by a player reached level 20, PC Gamer reported.

It is not difficult to get new recruits to "Hearthstone: Heroes of Warcraft", Blizzard explains. What a player should only do is send a recruitment email to any friend who does not play game yet using their Battle.net account. When the invited friend reaches level 20, Morgl the Murloc Oracle will join the card collection as a Shaman Hero. Also, the player will be given a Classic card pack if there are five level 20 invited friends in the list, Polygon reported.

All new recruits will also be given a Classic pack free-of-charge same as the player who invited them.

In addition to the Recruit a Friend feature, Blizzard's "Hearthstone: Heroes of Warcraft" also have added and changed a few features that can be read in "Hearthstone: Heroes of Warcraft" update log.
