Info

• Rhino lets out a forceful roar, increasing the damage output of his allies within 15 / 20 / 22 / 25 meters. Affected allies will gain 10% / 15% / 25% / 50% damage to all sources over a duration of 30 seconds.
  • Damage boost is affected by Power Strength.
  • Roar grants an additive bonus that's applied to your Warframe's total damage (weapon damage and ability damage). As an example, +30% power strength will increase the damage bonus to 0.5*1.3 = 65%. For a weapon that inflicts 250 damage, Roar will increase that value to 250*(1 + 0.65) = 412.5.
  • While Warframe ability damage is increased, Roar does not increase a Warframe's power strength. As such, Iron Skin does not gain durability from Roar.
  • Duration is affected by Power Duration.
  • Radius is affected by Power Range.
• The effects of Roar are applied to Rhino, Tenno, Companions, Hostages, Shadows, Specters, and hacked Shockwave MOAs.
• Allies only need to be in range at the time Roar is cast to gain its effects.
• Cannot be recast while active.

Tips & Tricks

• Increases the damage any ally deals from any source, so weapon damage as well as ability damage for the duration of the skill.
  • To gain the buff the ally needs be in range at the time of casting, entering it afterwards will not grant the damage boost.
  • The ally does not need to stay in range to keep the buff for its full duration.
  • Regardless of the range the caster will always get the buff.
• Multiple Roars do not stack.
  • A stronger Roar will overwrite a weaker one.
  • However if a weaker is cast, so that it last longer than a stronger (i.e., it is cast right before the stronger ran out or has higher duration due to increased Power duration) it will boost the damage after the stronger ran out.
