Dota 2 Aether Lens Guide by Psi-Clone

Basic Info

  • Range bonus affects item ability cast range as well.
  • Does not increase the range of auto-cast abilities such as Impetus or Searing Arrows.
  • Does not affect ability AoE radius, like Ravage.
  • Increases the damage of all abilities by 8%, even those that do not benefit from the range bonus.
  • This includes self-damage inflicted through abilities like Mist Coil and Double Edge.
  • Multiple Aether lenses additively increase magic damage but not cast range.
  • Aether lens affects cast range but not travel distance on some spells such as Sacred Arrow and Illuminate.
  • Increases travel distance but not width on cone shaped spells such as Breathe Fire, Dual Breath or Sonic Wave.
  • The spell damage bonus stacks and affects all damage types.
  • Cast range improvement does not stack with multiple Aether Lenses.
  • Cast range improvement affects targeted spells and distance related spells.


Sven’s Storm Hammer Deals 250 Damge at lvl 3.

With Aether Lens Equipped(8 % bonus) it will deal –

(250/100) * 8 = 20.

(Original + New 8%) 250 + 20 = 270

A Aether Lens Storm Hammer will deal 270 damage instead of 250.

Can be done with every hero – (Current Damage of spell/100)*8 = Extra damage .and then just add the extra damage to the original.
– – – – – – – – –

Normal Cast Range – 600
With Aether lens equipped range – 600 + 200 = 800
