League of Legends 15.21 Patch Notes Breakdown
Welcome to our patch notes breakdown for League of Legends Season 15.21!
Let’s break down all the new changes in LoL coming this week.
We recommend following along with the official patch notes since we won’t be listing all the specific stat changes, but rather focusing on the impact of the changes and the champions updated place in the current meta.
If you’re wondering how these changes will affect the meta, check out our LoL champion tier list!

Buffs, Nerfs, and Changes
Bard (buff)
- Bard’s W heal and movement speed are increased. It will make him a better Support on this patch!

Diana (nerf)
- Her Passive will deal less damage to jungle camps. This is a direct nerf to Jungle Diana. I expect we will not see her as much in the upcoming patches.

Dr Mundo (changed)
- His armor growth is increased.
- His bonus health scaling while his E is active has been reduced.

Ezreal (buff)
- Ezreal’s AD scaling is increased, which will make him a stronger ADC.

Graves (changed)
- Graves’ base magic resist is reduced.
- His E now grants additional magic resistance, based on his armor.

Gwen (changed)
- She has been reverted from previous changes. I would advise reading the image.

Kalista (buff)
- Kalista’s AD scaling is increased, which will make her a stronger ADC.

Kog’Maw (nerf)
- He gets less attack speed from his Q now.

Morgana (nerf)
- Her armor per level is reduced.
- This will make her weaker versus AD champions.

Quinn (nerf)
- Her Q damage is changed.
- Quinn’s R damage is weaker early, and now scales instead of being flat 70% damage.

Yone (buff)
- Base AD is increased, making him stronger in the Top and Mid roles.
Yunara (buff)
- Her W damage is changed.
- Yunara’s E movement speed is changed, the cooldown is increased, and a big bug has been fixed.
- These changes will make Yunara a little better.

Item Changes
Catalyst of Aeons
- The amount of health it provides is down.

Doran’s Blade
- Life steal is removed. It now heals for a percentage of the damage you deal.

Doran’s Ring
- Mana regen is now changed. It now grants more mana after damaging a champion, but gives less health regen.

Doran’s Shield
- Max heal is reduced.
Rune Changes
Second Wind
- Healing is reduced.
