The Bastion Corki comp is one of the safest choices in TFT Set 17. It combines a strong frontline with steady backline damage. As a result, it performs well in many different lobbies.
Corki is the main carry of the team. Meanwhile, Bastion champions protect him throughout the fight. Because of this, Corki gets enough time to cast multiple abilities and deal huge damage.
In addition, the comp is easy to learn. It does not require complicated positioning or rare items. Therefore, it is a great option for players who want consistent Top 4 finishes.

Bastion Corki Team Composition Overview
Active Traits
The final version of the composition typically activates:
- 4 Bastion
- 2 Fateweaver
- 2 Sniper
- 3 Meeple
- 2 Vanguard (situational)
- Additional utility traits depending on the match
Core Units
- Corki
- Rammus
- Aatrox
- Poppy
- Maokai
- Akali
- Caitlyn
- Kindred
In this setup, Corki serves as the primary carry. Meanwhile, Rammus, Aatrox, Poppy, and Maokai create a powerful frontline that absorbs damage and buys time for Corki to cast repeatedly. As a result, Corki can safely unleash his rockets and melt enemy teams.
Why Bastion Corki Is Strong
Powerful Frontline
The biggest strength of this comp is its frontline. Bastion units gain extra Armor and Magic Resist. Therefore, they can survive much longer than most tanks.
In addition, Rammus and Aatrox are naturally durable. Once they receive defensive items, they become very difficult to kill. As a result, Corki gets plenty of time to attack safely.
Reliable Damage
Corki deals damage to multiple enemies at once. His rockets can hit both the frontline and the backline. Because of this, he remains useful in every fight. Moreover, Corki scales well with common AD items. Therefore, building his items is usually straightforward.
Easy Transition
Many key units appear early in the game. For example, Poppy and Aatrox can help you win early fights. Meanwhile, Caitlyn can hold Corki’s items until you find him. Because of this, the comp has a smooth progression from the early game to the late game.
Weaknesses of Bastion Corki
Although the composition is powerful, it does have a few drawbacks.
- Corki 2-star is almost mandatory.
- The team loses a significant amount of damage if Corki lacks proper items.
- Assassin-style units can threaten the backline.
- The comp becomes difficult to play when multiple players contest Corki.
Because of these weaknesses, scouting the lobby is extremely important. If several players are already building Corki, you may need to pivot into another composition.
Best Items for Corki
Corki should always receive your damage items first.
Core Items
- Spear of Shojin
- Last Whisper
- Deathblade
Shojin helps Corki cast more often.
Meanwhile, Last Whisper reduces enemy armor.
Deathblade adds a large amount of attack damage.
Together, these items allow Corki to carry fights consistently.
Alternative Items
If you cannot build the ideal setup, use:
- Infinity Edge
- Giant Slayer
- Guinsoo’s Rageblade
- Blue Buff
These items still perform well. Therefore, do not hesitate to use them when needed.
Best Tank Items
Your frontline is just as important as Corki.
Rammus
Recommended items:
- Warmog’s Armor
- Bramble Vest
- Dragon’s Claw
These items increase both health and resistances.
As a result, Rammus can absorb massive amounts of damage.
Aatrox
Recommended items:
- Bloodthirster
- Sterak’s Gage
- Titan’s Resolve
These items make Aatrox much harder to kill.
Furthermore, they allow him to deal meaningful damage during long fights.Corki weakens the enemy team.
Best Augments for Bastion Corki
Choosing the right Augments can dramatically improve your performance.
Economy Augments
- Lottery Ticket
- Hedge Fund
- Buried Treasures
These Augments help you reach Level 8 faster. Consequently, you can find Corki and Rammus earlier than your opponents.
Combat Augments
- Ascension
- Jeweled Lotus
- Cybernetic Bulk
These choices improve your overall combat strength and increase your chances of maintaining a winning streak.
Trait Augments
- Bastion Crest
- Bastion Crown
- Fateweaver Crest
Naturally, trait-specific Augments are among the strongest options because they allow you to reach important breakpoints more easily.
Early Game Strategy
Start with the strongest board available.
A common Level 4 setup is:
- Aatrox
- Caitlyn
- Poppy
- Twisted Fate
This board offers both damage and durability.
If you find Shojin components early, build the item immediately.
As a result, you can often maintain a win streak.
Meanwhile, keep collecting Bastion units whenever possible.

Mid Game Strategy
At Level 6, your board should look like this:
- Aatrox
- Caitlyn
- Poppy
- Akali
- Milio
- Maokai
At this stage, focus on saving gold.
Then, push toward Level 8 as quickly as possible.
This approach keeps your economy healthy.
In addition, it gives you a strong chance to find Corki on time.

Late Game Strategy
Once you reach Level 8, roll for your main upgrades.
Your priorities are:
- Corki 2-star
- Rammus 2-star
- Aatrox 2-star
These upgrades increase your board strength dramatically.
After stabilizing, save gold and push Level 9.
Then, add extra utility or another powerful unit.
As a result, your late-game board becomes much stronger.

When Should You Play Bastion Corki?
This composition works best when:
- You obtain an early Spear of Shojin.
- Few players are contesting Corki.
- You have multiple BF Swords or Tears.
- You find Bastion units early.
On the other hand, if several opponents are forcing the same composition, you should consider transitioning into another Corki-related or Bastion-based setup.

Not only does it feature an incredibly durable frontline, but it also provides reliable backline damage through Corki.
