League of Legends has released a major update to mark the new season of 2021. And the much-loved game mode URF will also be revised in this 2021 version.

League of Legends: Interesting changes will appear in URF version 2021
Talk a bit about the URF mode of the previous versions where the player has a fixed 80% cooldown and no mana cost when using skills. This has created extremely impressive skill discharges, making each match dramatic and suffocating but equally "for fun". Back in 2021, Riot game revealed some changes to make this mode more balanced and attractive.
Cooldown changed to skill cooldown
Instead of 80% cooldown like before, the new URF version will provide 300 skill cooldowns to champions, and it can be stacked with other cooldown reduction sources. With the skill cooldown mechanism reworked in this new and cumulative version, players will be more comfortable creating gameplay than before.
The rune board will no longer be locked
Ngoc Paced Kills and Hunter Ultimate will no longer be locked in the new URF. This means that a champion can gain "huge" attack speed in the URF as well as the ultimate cooldown will be increased more than the old URF mode.
More balanced for mage champions using mana
If the player's champion uses mana, the mana gain from all sources will be converted to health at a rate of 40%. This makes the URF more balanced with the bonus mana not being wasted and mana-boosting items ignored due to the use of a resource-free skill.
Locks items that gain gold every 10 seconds
Items that increase gold every 10 seconds will be locked, in order to provide a better experience for new URF players.
