So recently they added a new [Atlas] augment that will allow him to do 2x more dmg and have a 2x faster first ability to use and your first ability will have NO ENERGY COST , [Path Of Statues] help you get the rubble to 1400 since you need 1400 rubble for the new augment to work , SO YOU DONT HAVE TO USE energy at all after you have the 1400 stacks of rubble since your [Path Of Statues] will get rubble for you and petrify enemies and your landslide will cost no energy at all ! Note that i also use gladiator mods on my sentinel and a [Mire] for stacking my landslide. Instad of [Augur Reach] u can use any mod of your preference , build however you want , this is just my approach .
