Radius: 900
Magic Damage Absorbed: 400
Duration: 12
Stack Limit Duration: 50
Cooldown 60 Mana 100


  • Interupts the user's channeling spells upon cast.
  • Does not affect heroes who have been affected by Barrier in the last 50 seconds.
    • A status buff icon on affected units shows how much time is left for it to be able to get affected again.
  • Barrier blocks damage before any reductions. The only exception here is spell immunity, during which it does not block any magic damage.

Insight Aura
Not blocked by Spell Immunity. Cannot be dispelled. Cannot be used by illusions.
Ability Affects
Aura Allies
Gives 4 health regeneration and 10% magic resistance to nearby allies.
Radius: 900
Health Regeneration Bonus: 4
Magic resistance bonus: 10%
Cannot be used by illusions. Illusions provide the aura, but do not benefit from it.


  • Stacks with all other sources of flat health regeneration and magic resistance, except with Insight Aura from multiple Pipes of Insight.
  • Does not provide the 10% magic resistance to the holder. However, placing a Pipe of Insight in your inventory while already being affected by Insight Aura's bonus magic resistance (from another Pipe of Insight, or from an illusion carrying the aura) will allow the holder to benefit from the full aura.
  • The aura's buff lingers for 0.5 seconds.

Additional Information[edit | edit source]

Pipe of Insight does not preserve Headdress's stat bonuses.

    • Stats: +30% Magic Resistance, +8 HP Regeneration, +5 Armor
    • Active: Barrier: Provides a 400 damage magic damage shield on nearby allied units. Affects Heroes and non-player creeps. If a unit already has this buff when another barrier is casted, it will override the buff with the new one instead of stacking additively. Buff lasts 8 seconds. Cooldown: 60. Mana cost: 100. AoE: 700.
      • Note: The 400 damage is before any magic reductions, not after. So a 300 damage spell removes 300 life from the shield, and not the 225 basic spell resistance. It is taken off the shield before it hits you, thus before any magic resistance is taken into effect.
