Lightning Shield


  • This ability got replaced by Ignite in the 6.00 gameplay patch.
  • Can be cast on any enemy, allied units and own units, except on self. Cannot be cast on wards and buildings.
  • Deals damage to enemy and allied units alike. Does not damage the unit the shield was put on.
  • Multiple shields can damage the same units.
  • Deals 18/24/30/36 damage in 0.5 second intervals.
  • Pre 5.80, Multicast used to cause this spell to be cast 1/2/3 extra times on random units (including self) within a 600 radius around Ogre Magi.
  • From 5.80 on, Multicast no longer caused it to be cast multiple times, but increased its damage per second and mana cost instead.
  • This is how much damage per second Lightning Shield dealt (before reductions) and how much mana it cost on each level with each level of Multicast:
    • Level 0 Multicast: 36/48/60/72 damage, 80 mana
    • Level 1 Multicast: 48/60/72/84 damage, 110 mana
    • Level 2 Multicast: 60/72/84/96 damage, 140 mana
    • Level 3 Multicast: 72/84/96/108 damage, 150 mana

  • Caused Fireblast to be cast 1/2/3 (Upgradable by Aghanim's Scepter. 2/3/4) additional times on the same target.
