Teamfight Tactics Set 15: K.O. Coliseum Release Date, Traits, Mechanics & More
/
Riot Games has revealed the next set for their auto battler Teamfight Tactics (TFT): K.O. Coliseum, the game's 15th set since launch. It’s a fighting game-themed update filled with colorful characters, fresh mechanics, and a twist on classic gameplay systems.
When does Teamfight Tactics K.O. Coliseum release?
The PBE servers for K.O. Coliseum go live on July 15, giving players a few weeks to test the new set. The full release is scheduled for July 30 on both PC and mobile platforms.
Soul Fighter: K.O. Coliseum – All Traits Listed
K.O. Coliseum introduces brand-new traits and origins, offering more variety and synergy options for players to experiment with.
Soul Fighter:
Can it truly be a fighting tournament without Soul Fighters? They've been training all their lives for this. Stronger together, they gain bonus health, as well as stacking Attack Damage and Ability Power every second up to 8 stacks! At max stacks, they unlock their max power, gaining true damage on their abilities and attacks.
Star Guardian:
True to the anime genre, Star Guardians power up through friendship. These magical champions gain a unique Teamwork Bonus for every Star Guardian on the board.
Crystal Gambit:
Crystal Gambit shows up in style. Kills and losses during player combats will earn players Gem Power. Every 4 player combats, it’s the player’s choice whether to cash out or double down. When doubling down, players gain 100% more Gem Power, but if the user wins, they’ll lose 50% Gem Power and cash out immediately.
Mighty Mech:
Get ready for “Me Mech” in chat again. Every Mighty Mech players field strengthens the Mighty Mech. The higher the star level, the more power!
Wraith:
Wraiths derive their power from the Shadow Realm, channeling it to strike the three closest enemies. But it’s not just all pain. The lowest health Wraith heals for 18% of the damage dealt by Wraiths and the Shadow Realm.
Battle Academia:
Grab your books - school is in session! Battle Academia units are constantly learning, unlocking their true potential, and upgrading their abilities.
Luchador:
Whatever one’s favorite wrestling move is, the Luchadors have perfected it. Gaining bonus Attack Damage, they get their second wind at 50% health, cleanse negative effects, heal, and leap into the ring to knock up their enemies.
Mentor:
The Mentors don’t exactly play well with each other, but if the player can entice all four of these champions to join their team, they’ll gain all bonuses and upgrade their abilities.
The Crew:
Better together, the crew gains health and Attack Speed for each Crew member fielded. Every 3-star Crew champion grants additional bonuses. Once enough of them are 3-starred, they’ll call in their starship to rain down destruction.
Supreme Cells:
To be The Supreme Cell, players have to do the most damage. All Cells gain Damage Amp, but the Supreme gains more and executes enemies under 10% health.
Stance Master (5-cost trait only):
As the 5-cost Stance Master, Lee Sin can pick a trait that’s best suited for battle. Choose between Duelist Stance, Executioner Stance, and Juggernaut Stance, and then gain a unique ability that matches the chosen stance.
Monster Trainer:
As a 3-cost Monster Trainer, Lulu stands out as TFT’s first champion that’s actually 3 units. When Lulu is played, she hops to the side and an armory of 3 monsters (Kog-Maw, Rammus and Smolder) pops up. Choose between Kog’Maw, who can zap the enemies; Rammus, who’s tanky and can stun his enemies by the power of durian; or Smolder, whose fiery sneeze makes him a lovable AD caster.
Prismatic Traits:
Historically, Prismatic Traits have required players to hit +2 or +3 of a specific trait—an intentionally difficult goal—in order to unlock a massive power spike. With K.O. Coliseum, Prismatic Traits will now require players to hit the highest breakpoint for the trait and then complete a mini-quest to unlock their Prismatic (and typically game winning) power. Players can spend a ridiculous amount of Mana with Star Guardians, collect all three Mighty Mech Augments, and more!
New Set Mechanic: Power Ups
K.O. Coliseum introduces Power Ups, a system that lets players customize Champions using Power Snax, adding flexibility and unique advantages.
The set will also introduce:
120 new Augments (70 of which are brand-new)
New cosmetics, including:
Chibi Spirit Blossom Lillia
Prestige Chibi Spirit Blossom Ahri
High Noon Thresh Unbound
The Veiled Village Arena
Anime-inspired Portal skins
Revamped Roles and Gameplay Changes
K.O. Coliseum also brings major changes to how units function in battle. According to Riot's press release, expect:
More melee carries
Unique unit roles with unusual ultimates and attack patterns
Mana gain reworks based on roles
More interaction with game systems
For example, Tanks will now gain 5 Mana per attack and also generate Mana by taking damage. This makes them more central to aggression and easier to target.
TFT Pro Circuit Begins August 2025
The new set also marks the launch of the game’s Teamfight Tactics Pro Circuit, a new tournament series that will be rolled out in four regions starting in August 2025, serving as another competitive layer for the game’s competitive esports scene.
Death Stranding 2: On the Beach delivers higher visual fidelity, consistent performance across the board, and a few new tricks that make gameplay more accessible, challenging, and fun. If you have the patience and come in with an open mind, you’ll be in an exclusive group of people who will struggle to describe this experience to anyone else.
