With Teamfight Tactics patch 11.5 , Riot will be looking to bring an overhaul to the entire Debuff system in the game.

Samira and Yone will be receiving some adjustments this time around, while Deathblade and Static Shiv are getting significant nerfs.

Teamfight Tactics fans looking for a detailed description of the patch can look up Riot's official website.

However for a brief overview, here are all the major highlights.

Teamfight Tactics patch 11.5 official notes

#1. Debuff overhaul

• Most debuffs in TFT are now part of a shared system, according to Riot. If an effect applies an already-active debuff on a champion, like multiple instances of an Armor Shred, for example, the strongest debuff will have priority for its full duration. Once the strongest debuff has worn off, if there’s a weaker debuff of the same type that would have lasted longer, the debuff will continue for the difference of the second debuff’s duration.
• This, Riot says, prevents “weird combos” of champions or items that would make enemies receive -100 percent armor, attack speed, etc. This change allows players to understand the debuffs at the same fast pace of the game. It also creates a standard debuff system that the devs can reference in the future, opening up “more unique champion kits” for the next set.
• Debuffs of the same type no longer stack together.
• In events where multiple debuffs of the same type occur on the same unit, the strongest will become the priority debuff for its duration.

• Fixed a bug where occasionally dead champions with trait items would retain all their items and could be bought or got off the carousel again
• Fixed Choncc’s audio
