Gall is a Ranged Assassinhero from the Warcraft universe, and a part that makes up the caster half of Cho'gall. This character is unique in that one player controls Gall while the other controls the Cho half of the hero.
Though Cho'gall was extremely powerful, he was also dangerously insane. The Twilight's Hammer clan, less of a tribe and more of a religious cult, was devoted to bringing about the apocalypse. In his capacity as a chieftain and as the right hand of Gul'dan, Cho'gall aided his master in the creation of the death knights and the Altars of Storms, and in the transformation of normal ogres into ogre magi.
Gall is the Assassin part of the Cho'gall. The player who controls Gall is in charge of using only Ranged Basic Abilities, while the one controlling Cho is responsible for the Hero's movement and Basic Attacks. Therefore, the two players must have synergy and communication to syncronize their abilities to maximize Cho'gall's potential.
Overall, Cho'gall has a very niche role that requires planning and adaptation from the rest of the team composition, as two players controlling one Hero essentially means one less Hero in lanes. On the other hand, Cho'gall is perfectly capable of solo laning given his wide range of abilities and remarkable solo sustain.
Quest: Hitting enemy Heroes affected by Consuming Blaze with Shadowflame lowers the cooldown of Shadowflame by 1 second. Reward: After doing this 20 times, permanently lower the cooldown of Shadowflame by 1 second.
Shadowflame Build: focused on maximizing Shadowflame's damage and utility. Recommended for most situations, and pairs well with Cho regardless of what build he picks. However, should he pick Upheaval, then picking Twisting Nether is recommended instead to maximize its synergy.
Make sure to always pay attention to Cho'gall's current trait, as his damage output and survability is great enhanced/decreased depending on which one is active.
Aside from the glowing icon in the action bar, a small glyph appears directly below Cho'gall as a visual indicator for each trait: Ogre Hide appears as orange, and Ogre Rage as purple.
Shadowflame should be used whenever it's off-cooldown, since it has very low cooldown.
Poke structures Dread Orb whenever possible to take advantage of its long range.
The distance Dread Orb travel is directly related to the distance between the target area and Cho'gall: the closest the cursor is to Cho'gall, the shortest will be the bounce distance. Keep this in mind when using it against targets at close range.
Try to detonate Runic Blast in order to hit as many opponents as possible to maximize its area of effect.
(Patch September 13, 2016) Note:Fixed an issue that could cause Tyrael, Uther, and Gall players to incorrectly receive AFK Warnings due to the combination of their post-death effects and lengthy death timers at later levels.
(Patch May 17, 2016) Note:Fixed an issue that could cause Abathur and Gall players to be flagged as AFK if they did not move from the starting area, despite issuing commands to their Heroes.
(Patch March 1, 2016) Note:Gall will no longer be separated from Cho after manually exiting a Dragon Knight or Garden Terror.
