What Is the Ancient War Construct?

First of all, the Ancient War Construct is a special 5-cost unit that can only be summoned through the Prismatic Augment Heart of the Hazard. Unlike traditional units, it does not belong to any trait or synergy. However, because of that, it compensates with extremely high base stats and a devastating ability.

In addition, this unit acts almost like a “final boss” in your composition. Therefore, once summoned, it can single-handedly swing fights in your favor.

How to Unlock the Ancient War Construct

Initially, the requirements for activating Heart of the Hazard were extremely difficult:

Reach Level 10
Own 6 unique 3-star units

However, because this was nearly impossible in ranked games, Riot adjusted the conditions. Consequently, the new requirements are much more achievable.

Updated Requirements:

Reach Level 9
Still need 6 unique 3-star units
Additionally, you receive 1 Rek’Sai (2-star), 1 Bel’Veth and 1 Briar

As a result, players now have:

Better early-game stability
More frontline strength
Higher chances to survive until late game

Therefore, this change transforms the augment from unrealistic to situationally viable.

Base Stats of the Ancient War Construct

Now, let’s take a closer look at its stats:

Health: 5000 / 9000 / 16200
Attack Damage: 90 / 135 / 203
Armor & Magic Resist: 90
Mana: 50 / 100

Analysis:

Clearly, these numbers are far above average. On the one hand, the massive HP pool allows it to tank huge amounts of damage. On the other hand, its respectable attack stats ensure it still contributes meaningful DPS.

Thus, it functions as both a primary tank and a secondary carry, which is extremely valuable in late-game scenarios.

Ability Breakdown: Sword Storm Devastation

More importantly, its ability is what truly makes it terrifying.

It summons multiple swords that strike enemies in a grid pattern
Upon activation:
- 20 swords converge
- Deal massive damage to the main target
- Splash damage to adjacent enemies

Why this is powerful:

First, it deals AoE damage, which is crucial in TFT
Second, it can hit backline units
Third, it creates enormous teamfight pressure

Therefore, if positioned correctly, it can wipe entire enemy teams in seconds.

Why the Ancient War Construct Can Dominate the Meta

There are several reasons why this unit is expected to become meta-defining.

Unrestricted Power

Because it has no trait, it does not rely on synergies. As a result, you can slot it into almost any composition.

High Comeback Potential

Even if you are behind, once you summon it:

You gain a massive power spike
You can immediately stabilize

Thus, it acts as a powerful comeback mechanic.

Strong Snowball Effect

After unlocking it:

You can maintain win streaks more easily
You pressure the entire lobby

Consequently, it becomes a late-game win condition.

How to Play Around the Ancient War Construct

Early Game

At the beginning, you should:

Focus on preserving HP
Play strong early boards
Utilize Rek’Sai for frontline

At the same time, you should plan your economy carefully.

Mid Game

Next, during mid game:

Slow roll for 3-star units
Maintain a healthy gold balance
Avoid over-rolling

Meanwhile, you must balance:

Economy
Board strength
Upgrade timing

Late Game

Finally, in late game:

Rush Level 9
Complete 6 three-star units
Activate the augment

Once you summon the Ancient War Construct:

Protect it with your team
Position it for maximum AoE impact

As a result, your board becomes significantly stronger.

Best Items for the Ancient War Construct

Even though it has no traits, items still matter a lot.

Defensive Items:

Armor
Magic resist
Healing

Offensive Items:

Attack damage
Critical strike
Armor penetration

Therefore, depending on your needs, you can build it as:

A main tank
Or a hybrid damage dealer

Weaknesses You Should Know

Despite its power, it is not without flaws.

First, the activation condition is still difficult
Second, it relies heavily on hitting 3-star units
Third, it can be countered by crowd control

Thus, if you fail to meet the conditions, your game plan may collapse.

Should You Play This Strategy?

The answer is: Yes—but situationally.

You should play it if:

You get Heart of the Hazard
Your lobby is not too contested
You have a strong early game

You should avoid it if:

Too many players contest your units
You are low HP early
Your rolls are unlucky

Therefore, this is a high-risk, high-reward strategy.

Conclusion

In conclusion, the Ancient War Construct is one of the most exciting additions in TFT Set 17.2. Not only does it offer incredible power, but it also introduces a new strategic layer to the game. Furthermore, its ability to turn fights and carry late-game boards makes it a serious meta contender.
