As a result, Riot Games is implementing a buff in response to the nerfing of Grasp of the Undying in League of Legends patch 14.21 preview. This adjustment aims to maintain a consistent power level for melee carries in light of the recent reduction in the effectiveness of the Blade of the Ruined King.Since AP remains somewhat excessive and is particularly overshadowing Lucidity, the developer has decided to reduce the effectiveness of Sorcerer's Shoes in the League of Legends patch 14.21 preview. This decision stems from the observation that Lucidity is currently in a satisfactory position and does not require any enhancements at this time.Also read: LoLdle answers 831 (Tuesday, October 15, 2024)Bounty changes in League of Legends patch 14.21 previewThis League of Legends patch 14.21 preview also introduces notable adjustments to Bounties, aimed at enhancing their intuitiveness when it comes to both champion and objective Bounties. In essence, the relationship between gold earned and gold spent will become more closely aligned with Bounties.In the context of Bounties, players exhibiting a negative status will gradually return to a baseline of 0 gold through the acquisition of gold. This is in contrast to a player who has experienced multiple deaths and subsequently achieved an elimination, resulting in a Bounty of 150g. Achieving one to two eliminations may not be enough to restore a player's worth to 300g.Moreover, the repeated elimination of players will result in a lower acquisition of Bounty and a diminished amount of gold. Simultaneously, Objective Bounties will be adjusted to rely more on gold rather than experience points (XP), aligning more closely with player preferences.This concludes the League of Legends patch 14.21 preview.Check out more LoL news updates below:All qualified teams for LoL Worlds 2024All broadcast talent at LoL Worlds 2024League of Legends patch 14.18
