From Destinypedia, the Destiny wiki
These empowered hulking beasts constantly move in towards their opponents while rapidly shredding through their health with their powerful Overcharged Ether blasts. When they get close enough, they will unleash an Arc ground slam that does tremendous damage and sends players flying backward, further than a normal Abomination’s slam attack would. Their rage is enhanced by extreme durability and an inability to be staggered as they charge toward their foes. The only way to halt their approach would be with seasonal Anti-Unstoppable mods, which temporarily stun them and leave them open to attack and more damage.
