U.R.F. Mode

For the Main article, see April Fools Day.

Ultra Rapid Fire (URF) and New Ultra Rapid Fire (N.U.R.F.) are game modes for April Fools' day. It is exclusively on Summoner's Rift for both Normal Game and Co-op vs. AI. It also introduces a new game type called "Blind Draft" where 3 champs are banned by both teams, then blind pick commences.


Awesome Buff of Awesomely Awesome Buffing

A number of stats have been buffed significantly, and standard caps for some bonuses have been raised, including:


  • This unit does tons of damage.
  • No poros were harmed in the making of this game mode.
Tons Of Damage!
  • All health pools and damage dealt are multiplied by 1000. In the HUD this will be shortened to K form.
  • The death recap will show damage taken as TONS (X%), where X is the percentage of your maximum health taken.
Removed Level Cap

Champions will continue to level-up beyond level 18.

  • Level cap is now 30.
  • The amount of experience required to level up continues to increase at the same rate.
  • A champion's base stats will continue to increase at the same rate, but no other scaling is affected.
  • No additional skill points are awarded.
Heal Embargo

In order to overcome the lustful thirst of blood greedy players, healing is tuned down from the beginning, but scales up to be nullified as the game progresses.

  • All direct healing effects are 50% less effective at the beginning of the game, increasing by 1% every 30 second, up to 100% effective at 25 minutes.
Shield Overload

In order to make more just at the eye of our Lord Urf Urf, shields are tuned down to compensate the now spammable spell to which they belong.

Unveiling the future of League of Legends


BY PABRO[1] "What we’re calling New Ultra Rapid Fire raises the stakes by delivering a slow, sophisticated, and stoic strategic showcase that tests teams’ abilities in new and dynamic ways while not restricting the highest tier of play to those with sub-millisecond response times." Continue reading for more on the most intense gamemode yet: N.U.R.F!

Almost one year ago, we debuted a new way to play League of Legends in a silly, fun game mode that turned competitive balance on its head in celebration of the yearly troll-fest known as April Fools. While we were ultimately kidding, many of our designers saw the opportunity to work on a true evolution of League gameplay inspired by URF. After reviewing player feedback and hammering out brass tacks, we felt confident we created the most refined gameplay experience League has inspired yet, all in time to iterate in preparation of the next competitive season.

What we’re calling New Ultra Rapid Fire raises the stakes by delivering a slow, sophisticated, and stoic strategic showcase that tests teams’ abilities in new and dynamic ways while not restricting the highest tier of play to those with sub-millisecond response times.

Normally, a League match is a fast-paced slugfest that ranges from top to bottom lane and across Summoner’s Rift. We want to broaden the pool of high-level talent to include expert tacticians previously excluded by something so trivial as the necessity of hyper-twitch reflexes.

There’s a lot to talk about, but with the entirely accidental leaks of some New Ultra Rapid Fire assets, we thought it’d be better to just show you. Tomorrow, we’ll release the proverbial kraken known as New Ultra Rapid Fire to live servers.

Here’s a preview of some of the gameplay refinements coming tomorrow night when New Ultra Rapid Fire debuts:

  • +100% mana and energy cost on all abilities
  • +200% cooldown inflation on abilities, items and summoner spells
  • +225 movement speed reduction
  • +200% delay between basic attacks
  • Critical strikes deal 50% of base AD
  • Units critically strike on 150% of attacks

Will the upper limit of the potential for human competition skyrocket with the introduction of New Ultra Rapid Fire? Can you rise to the resulting challenge? Can a mere man defeat a manatee? When it comes to League of Legends, that last answer is indubitably yes, but no matter. The gauntlet is thrown. Hoist it at thine own risk.""

BY L4T3NCY "Heya guys,

I want to jump in an give a little more design context as to why we moved in the direction we did for New Ultra Rapid Fire this year. We've always mentioned that we want to "improve and innovate" on each mode before it comes back, not just release the same thing. There will always be things that could have been done better, and this way we can tweak and improve them to provide a better experience than the 1st time around.

We heard you guys loud and clear that you didn't want Ultra Rapid Fire on Howling Abyss, so we've kept New Ultra Rapid Fire on Summoner's Rift. SR has more strategic choice designed into it anyway, which is given even more importance in NURF mode.

Positioning in team fights, choosing when to go for objectives (if at all) and minion wave management is crucial. NURF mode punishes mistakes pretty hard (which conveniently ends games quickly and prevents them from dragging on too long). Your League play is going to level up."

Ultra Rapid Fire Preview

  • 2014 U.R.F. Crest
  • U.R.F. mode (Illustration)
  • Awesome Buff of Awesomely Awesome Buffing
  • New Ultra Rapid Fire (N.U.R.F.) teaser snapshot
  • 2015 U.R.F. Crest
  • Strategic Buff of Strategistic Strategy


  • Building Cooldown Reduction will NOT add to the Cooldown Reduction already provided by the buff.
    • Because of this, the Crest of the Ancient Golem.png Crest of the Ancient Golem is completely useless in this map, as it will not give any extra Cooldown Reduction and the Mana/Energy Regen is wasted thanks to everyone having essentially unlimited mana.
  • On the 2014 version, a champion must have had sufficient maximum mana in order to activate the ability. Realistically, only Swain Swain's Ravenous Flock.png Ravenous Flock was affected and the ability would toggle-off once the cost scaled beyond Swain's maximum mana. As of 2015, ability costs are now removed.
  • Ultra Rapid Fire can be abbreviated to U.R.F, a clear reference to Urf Urf, a previous Riot joke.
  • The "This unit is currently able to traverse the Abyss" is possibly a reference to Dark Souls, where the player requires to equip a certain item to traverse "The Abyss" and fight a certain boss. The Abyss is also another name for The Void.
  • The event was meant to end on April 7, but was extended to April 13 due to the positive feedback. They also disabled the use of more champions.
  • The "Defeat" banner was replaced with a "2nd Place" banner at the end of a game in this mode.
  • In death recap of U.R.F. 2015, all damage text were replaced by "TONS", which is a reference to "Tons of damage."
