Fortify was a 'non-targeted' summoner spell that buffed your turrets globally. Fortify was removed from League of Legends with the November 15th, 2011 patch V1.0.0.129.


Fortify was mainly used defensively to prevent turrets from taking damage and clearing minions faster than normally. However it was also a very effective method to punish turret divers or quickly do damage to foes that got caught by pulls and taunts like Rocket Grab.png Rocket Grab and Puncturing Taunt.png Puncturing Taunt.


  • When you use Fortify, any hits to the protected tower won't proc certain abilities that would have worked before. For example, Jax Jax's Relentless Assault.png Relentless Assault, Guinsoo's Rageblade item.png Guinsoo's Rageblade, and Master Yi Master Yi's Double Strike.png Double Strike.
  • Fortify can be used while your champion is dead.
  • While fortified, a turret grants you assists and kills when it last-hits or assists in killing an enemy champion as if you were dealing the damage, and not the turret. This does not, however, apply to minion kills.


  • The bonus damage to minions is an on-hit effect and only applies to standard attacks and abilities that specifically mention applying on-hit effects (e.g. Ezreal Ezreal's Mystic Shot.png Mystic Shot or Nasus Nasus' Siphoning Strike.png Siphoning Strike).
  • After the V1.0.0.129 patch update, players who achieved summoner level 4 reported having the message that they have learned Fortify. This tooltip may have been left out during the patch's installation.
