Master Zio's Turn-One Combat Readiness in Epic Seven

In the competitive arena of Epic Seven, securing the first turn can dictate the entire match. Zio, the Moonlight 5-star Mage, is a premier counter-cleave unit designed to shut down high-speed openers. Unlike traditional speed contesters who require extreme 300+ speed gear, Zio relies on his unique passive skill, Supreme Authority, which grants him a massive Combat Readiness (CR) push at the start of the battle.

To easily find your target speed requirements and ensure you never get outsped by speed RNG, use our interactive Epic Seven Zio Speed Calculator above. You can adjust your passive skill level, configure custom starting CR RNG, and run the real-time Combat Readiness track simulator to visualize the opening turn order.

How Zio's CR Push Translates to Speed

Zio's passive skill provides a 20% to 30% Combat Readiness push at the start of the first battle, depending on his skill enhancement level. Because this is a CR push rather than a flat speed multiplier, Zio is effectively starting the race closer to the 100% finish line.

To calculate Zio's required speed to move before an opponent, we model the time it takes for each unit to cover their remaining distance:

• The opponent must travel $100\%$ ($1.0$) of the CR track.

• Zio must only travel $100\% - \text{CR Push\%}$ of the track.

Without factoring in the game's start-of-battle speed RNG, the flat relationship is: $S*{zio} = S*{opp} \times (1.0 - P\_{zio})$

Where $S_{zio}$ is Zio's speed, $S_{opp}$ is the opponent's speed, and $P_{zio}$ is Zio's passive CR push percentage. At max skill level (+30% CR push): $S*{zio} = S*{opp} \times 0.70 \implies S*{opp} = \frac{S*{zio}}{0.70}$

This means a Zio built with 240 Speed behaves as if he has 342.8 Speed on the opening turn, easily outspeeding standard high-speed units.

Speed RNG and Guaranteed Outspeed Calculations

Epic Seven introduces a random 0% to 5% starting Combat Readiness variance to every unit at the start of battle. This random speed fluctuation (Speed RNG) means that to guarantee Zio takes the first turn, you must account for the worst-case scenario: the opponent rolls a +5% CR boost while Zio rolls 0%.

1. Guaranteed Outspeed (100% Win Rate)

To be absolutely safe against speed RNG, Zio must satisfy: $S*{zio} \geq S*{opp} \times \frac{1.0 - P*{zio}}{0.95}$ At max passive skill (+30% CR push): $S*{zio} \geq S\_{opp} \times 0.7368$

2. Speed Tie / Average (50% Win Rate)

When both units roll the same starting CR RNG: $S*{zio} \geq S*{opp} \times 0.70$

3. Chance to Outspeed (Lucky Cut)

If Zio rolls +5% CR and the opponent rolls 0% CR, Zio can cut in even with lower speed: $S*{zio} \geq S*{opp} \times 0.65$

Core Openers and Target Matchups

Understanding Zio's speed is essential when facing top-tier speed openers like Ran, Peira, Conqueror Lilias, and Amid.

Frequently Asked Questions (FAQ)

Q: Can Zio's passive CR push be reduced by Politis or Solitaria?
A: No. Zio's passive, Supreme Authority, contains a unique clause making him unaffected by effects that reduce Combat Readiness increases received. His opening 30% CR push is completely immune to passive counters like Politis or Solitaria of the Snow. You can read more about his official skill details on the Epic Seven Stove Forum.

Q: What are the best artifacts for Zio to secure and utilize his first turn?
A: Zio is commonly equipped with Tagehel's Ancient Book to secure Souls for the team, or damage-boosting artifacts like Portrait of the Saviors to maximize his S3 output. High-rank players also run Lela Violin or Bloody Rose depending on their team utility. Check build details on community databases like Epic7x Hero Database.

Q: Does Speed Imprint affect Zio's calculations?
A: Yes. Speed Imprints from heroes like Vildred, Helga, or W Schuri apply to the character's base speed before the battle. If your team or the opponent's team has Speed Imprints, you must add those speed values to the base speed inputs in the calculator.
