Ultra Rapid Fire

		"He took an axe and split himself in two— right down the middle." It has been suggested that this article or section be split into distinct URF and ARURF articles or sections. Reason given: ARURF hasn't 'succeeded' URF: they are both on rotation. If you wish to discuss this, please explain why here.

U.R.F. Mode

Ultra Rapid Fire (U.R.F.) is a Featured Game Mode played on Summoners Rift where all champions get to use their abilities more often and matches usually last 20 minutes or less. All players start the game with an aura that adds many adjustments to how the game is played. The two main highlights are 300 Ability haste, (equivalent to 75% cooldown reduction), and the removal of all mana and energy costs from using abilities.

As of February 4th, 2021, All Random Ultra Rapid Fire (A.R.U.R.F.) is available to play. Players get a random champion chosen for them based on what they own and what is part of the free to play rotation. This is the only major change compared to the original URF, where you could choose your champions. The game mode is expected to be available till March 8th, 2021.

Mode-Specific Changes

As balanced changes from previous events have been observed in-game despite not being documented by Riot, all possible recurring changes have been listed below and appropriately denoted. The reason for distinguishing these changes is that the values listed are those from previous event notes and may not reflect the current value.

Note that any cooldowns detailed below are as they appear in-game (i.e. they are not reduced by Ultra Rapid buff to a lower value).

Patch and Buff History

Main article: Patch and Buff History

Trivia

• General
• Development

• Ultra Rapid Fire was first introduced for April Fools' Day. To celebrate the 10th Anniversary of League of Legends' release, U.R.F. was brought back as an experiment.
• The mode's name, Ultra Rapid Fire, was likely chosen because its initials spell Urf, Riot's April Fool's mascot.
• The event was meant to end on April 7 on its first year of release, but was extended to April 13 due to the positive feedback. They also disabled the use of more champions.
• "Defeat" used to be replaced with "2nd Place" in the post-game lobby.
  • This change was also present in-game when the Nexus was destroyed in early versions of URF, but was removed when Riot updated the game client's announcement assets.
• ARURF was around 20-25% of hours by the end of the last long run.
• The icon for the in-game Awesome Buff of Awesomely Awesome Buffing is edited from Urf's appearance in the Welcome to Planet Urf login screen.
  • The old icon for the buff might have been reused from another buff or effect icon.
• Nexus Blitz, another featured game mode, borrows the Awesome Buff of Awesomely Awesome Buffing and the URF mode's namesake in its URF Deathmate event.
• In the 2014 version, a champion must have had sufficient maximum mana in order to activate the ability. Realistically, only pre-rework Swain's Ravenous Flock was affected and the ability would toggle-off once the cost scaled beyond Swain's maximum mana. As of 2015, ability mana costs are now completely removed.
• In the 2015 version, the exact numbers of damage received in the Death Recap was replaced "TONS", referencing David 'Phreak' Turley's catchphrase in Champion Spotlights as well as the meme around it. The percentages were still visible, though.
  • For example: Javelin Toss: TONS (93%) Magic Damage; Swipe: TONS (7%) Magic Damage
• In 2019, URF was confirmed to be coming back with all champions available on October 28th through November 8th for the 10th Anniversary Event.
  • This was also the first time in over 4 years in which pick-based URF made its return.
• Prior to the 2020 version, Mana was not considered to be expended for the purposes of Eternity (i.e. you do not restore health), but was for the purposes of Mana Charge (i.e. you can increase your maximum mana for Manamune or Archangel's Staff.
  • Seraph's Embrace's Mana Shield does not grant any shield. This is likely a bug caused by the fact no mana is consumed, and so none is converted into a shield.
• In the 2021 version, the new Awesome Buff of Awesomely Awesome Buffing effect of bonus mana regeneration being converted into bonus health regeneration was coincidentally predated by the V4.01 April Fools' Day patch:

  We needed a way to make manaless champion even better in the current meta and this seem like the best way achieve our goal as it opens new build paths that were normally discarded because of the existence of mana regeneration.

  • Any excess mana regeneration that is not being used will now be converted to health regeneration for the champion.
• The bottom-two nonsensical 'buffs' and 'sources' in the in-game tooltip for the Awesome Buff of Awesomely Awesome Buffing have made several references to numerous inside jokes, pop culture references and League of Legends features over the years;

• URF 2020
• URF 2019
• ARURF 2019
• ARURF 2019 (Twitter Teaser)
• ?
• URF 2017(?)
• URF 2015

Unveiling the future of League of Legends (N.U.R.F.)

By Paul 'Pabro' Bellezza

"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
• Abilities - 100% increased for Mana and Energy consumption.
• Cooldown reduction - 200% Cooldown Inflation on abilities, activated items, and summoner spells.
• Tenacity - 50% increased crowd control duration (excluding airborne and suppression).
• Movement speed - 225 Movement Speed Reduction.
• Attack speed - 200% delay increase on basic attacks.
• Critical strike - Critical strikes are modified to deal 50% AD and all champions have 150% critical strike chance.

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."
