Info

• Atlas summons two rock golems that automatically engage nearby enemies. Each Rumbler possesses 500 / 750 / 1000 / 1200 health, 50 / 150 / 250 / 500 armor, and a speed multiplier of 1. Rumblers inflict 800 / 1000 / 1400 / 2000 damage with each melee attack and can occasionally throw stones at enemies that inflict 200 / 250 / 350 / 500 damage. Rumblers last for 15 / 20 / 30 / 45 seconds.
  • Physical size of each Rumbler along with their health, armor, and all sources of damage are affected by Power Strength. Health and armor are also affected by Warframe health, shield, and armor mods.
  • Rumbler health uses the following expression when accounting for Power Strength: Modified Health = Health × (1 + Base Health Bonus + Base Shield Bonus + Power Strength).
    • For example, with Vitality, Redirection, Intensify, and Atlas all at max rank, rank-3 Rumblers will have a modified health of 1200 × (1 + 2 + 4.4 + 2 + 4.4 + 0.3) = 16920.
    • Atlas' rank influences Rumbler health as the "Base Health Bonus" and "Base Shield Bonus" in the expression are referring to bonuses applied to Atlas' respective base stats. As Atlas at max rank will have 300 health and 300 shields (from 100 health and shields at rank 0), the +200% health and shield increase will also apply to Rumbler health.
  • Rumbler armor uses the following expression when accounting for Power Strength: Modified Armor = Armor × (1 + Base Armor Bonus + Power Strength).
    • For example, with a maxed Steel Fiber and Intensify, rank-3 Rumblers will have a modified armor value of 500 × (1 + 1.1 + 0.3) = 1200.
  • Melee attacks stagger enemies on each hit, and enemies damaged by thrown stones are ragdolled.
  • Duration is affected by Power Duration
  • Speed multiplier is affected by Power Range and cannot fall below 0.5 or exceed 1.5 under any circumstances.
• If the ability is deactivated by pressing the ability key again (4 ) or Atlas becomes incapacitated, active Rumblers will self-destruct and inflict 500 / 750 / 1000 / 1250 damage to enemies within a radius of 3 / 4 / 5 / 6 meters.
  • Explosion damage is affected by Power Strength.
  • Damage does not bypass obstacles in the environment and diminishes with distance.
  • Explosion radius is affected by Power Range.
• Rumblers are immune to status effects, such as knockdowns and Bleed procs, but can be staggered.
• While melee kills by the Rumblers are considered melee kills by Atlas, they do not contribute to the Melee Combo Counter.
• Rumblers have collision detection for enemies only. Atlas and allies can move through Rumblers unobstructed.
• Atlas can maintain only two Rumblers at a time.
  • The number of active Rumblers is displayed in the HUD beside Atlas' shield and health indicators, and waypoints are displayed onscreen for each active Rumbler.
• Cast delay of 2.5 seconds is affected by Natural Talent.
