Ultra Rapid Fire art

U.R.F. Mode

Ultra Rapid Fire (U.R.F.) is a Featured Game Mode that was first introduced for April Fools' Day that, in a nutshell, grants all players 80% cooldown reduction and removes ability costs. The mode has since been succeeded by All Random Ultra Rapid Fire (A.R.U.R.F.), which follows the same gameplay but now utilizes the All Random draft type instead of Blind With Bans. To celebrate the 10th Anniversary of League of Legends' release, U.R.F. was brought back as an experiment.[1]

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).

This table extracts the data from Module:ChampionData/data and Template:urf changes/data.

Trivia

  • Before URF2020, Mana is not considered to be expended for the purposes of Eternity (i.e. you do not restore health), but is for the purposes of Mana Charge (i.e. you can increase your maximum mana for Manamune item Manamune or Archangel's Staff item Archangel's Staff.
    • Seraph's Embrace item 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.
  • Cooldown Reduction cannot be increased beyond the 80% granted by the Awesome Buff.
  • On the 2014 version, a champion must have had sufficient maximum mana in order to activate the ability. Realistically, only pre-rework Swain OriginalSquare old2 Swain's Ravenous Flock old 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.
  • The name, Ultra Rapid Fire, was likely chosen because its initials spell UrfSquare Urf, Riot's April Fool's mascot.
  • 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 initial 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.
  • "Defeat" is 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.

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

"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."
