    • 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.
