Overview.

Double Strike” is a power-up that provides one additional attack with a 25% chance for each normal attack.

While not a simple increase in attack speed, it produces a tremendous increase in damage in certain situations.

This article explains the details of how it works, compatible champions/items, and when to take it.

Basic Specifications of Double Strike

The Double Strike has a 25% chance of launching one additional attack for each normal attack.

This decision is independent, and theoretically may be triggered consecutively.

In the actual play footage, scenes of four consecutive triggering have been confirmed, and it also features a pseudo-randomness that makes it easier to trigger at the end of the game if the number of triggers in the early stages is low.

The double strike does not simply increase the attack speed, but cancels the rigid motion after a normal attack, resulting in a shorter total attack time.

(In many cases, guinsaw holders can use Double Strike.)

Difference between Double Strike and Attack Speed

It does not simply increase attack speed, but cancels the “hardening motion after the attack”.

• Example: Jin’s normal attack is “145 frames” → “60 frames” when Double Strike is activated.
  (It can be estimated that the pre-attack motion is about 40% of the total attack time)

Mathematically calculating the expected value, the average number of additional attacks occurs 1/3 times.

The expected total number of frames is 145 + 20 = 165 frames; the average time per attack is 123.75 frames, which is approximately a 17.2% increase in attack speed over the original 145 frames.

This remains constant whether the attack speed is 1.0 or 5.0.

Strengths and Compatibility of Double Strike

The 17% increase is numerically inferior to the 25% increase of “Shadow Divider” and “Storm Bender”.

However, the situation changes significantly when considering champions or items with on-hit effects.

In particular, great synergy occurs in the following cases

Champion: Cog-Maw
Items: Flicker Blade, Wit’s End, Static Shiv, Titan Hydra

All of these characters and items show their true value by increasing the number of times a normal attack is triggered, and even a mere 17% increase in attack speed can increase damage by about 25%.

Double strikes, which may seem subtle when looking at the numbers alone, can be a very powerful option depending on the conditions.

(When combined with these, it evolves into a very powerful power-up!)

Conclusion

Double Strike is a probability-activated type of additional attack, and is designed to shorten the total attack time.

The rate of increase in attack speed is constant at about 17%.

Although numerically inferior to other power-ups, it is very powerful when combined with normal attack effects and specific items.

It is more suitable for sub-carry than main carry, and depending on conditions, it can greatly increase damage.

(Example of combining with Cog-Maw, which is as powerful as Stormbender)

Impression

Through this verification, we felt that “Double Strike” is a power-up that should not be evaluated based on numbers alone.

If we look at the simple attack speed increase rate, it is about 17%, which is not enough, and it looks inferior to “shadow alter ego” and “stormbender,” which give a 25% increase.

However, once we understood how it works, we realized that its true value is completely different!

I felt that it is not just a “faster punch”, but a profound power-up that can become a big deal depending on the player’s understanding and construction skills.
