While the premise of the map is similar, the map is not. Various changes have been made to the original iteration of the Rak’Shir duel - much like how Lock & Load was changed.

The original “Rak’Shir” map from Legacy of the Void’s campaign.

The new “Chains of Ascension” map. Note the expanded map size, higher unit density, and doubled natural expansions.

The concept of “Chains of Ascension” is simple. Build up an army, and keep as many units as possible next to the two Tal’darim combatants to push your ally to the end of the map. While the mission’s description is easy, it is not as relaxed as it sounds as the enemy will likely send more than enough of its own units to push you and your ally into a corner.

Those who are feeling adventurous can also try their luck at slaying the Slayn Elementals. These creatures will roam the map, and if you are unfortunate enough to run into them while the enemy is pushing their Champion down the lane, you may be caught in the crossfire. Take these out as soon as possible for experience points bonus as well as an easier time commanding the action.

While an official release date hasn’t been announced for patch 3.2.0 yet, it will likely be released alongside Nova Covert Ops on March 29th. Until then, stay strong commanders!
