Iso is a Chinese Duelist and specialist in risky contracts: he protects himself with an energy shield, makes his targets vulnerable and isolates an enemy in a duel to the death.

Iso

Playstyle

Iso wins through duels. You open with the Contingency wall to enter under cover, make an enemy vulnerable and suppressed through walls with Undercut, then activate Double Tap before the first shot to absorb a burst. The energy orbs created by your targets extend the flow state and refresh the shield. Your ultimate isolates a single opponent in a 1v1: pick the one who bothers you most, for example an Operator player. Iso demands good aim, because almost everything is settled by shooting, and composure to get out of the arena.

Abilities

Key CBasic

Contingency

200 credits · 1 charge

You project an energy wall that stops bullets. Primary fire launches it fast, alternate fire makes it advance at half the speed. It serves as cover to move forward or change angles during an entry.

Key numbers

  • Minimum wall duration: 4.6 s
  • Alternate fire: the wall advances at half speed
  • Use alternate fire to advance slowly with the wall and stay protected on an open site.
  • Throw it on the line of an Operator before leaving your cover so they lose their angle.
  • Place it to cut a duel, then go around it with your team instead of staying behind it.
Key QBasic

Undercut

300 credits · 1 charge

A molecular bolt that passes through walls and solid objects. Players it hits become vulnerable and are suppressed for 4 s. You then step out on them while they can no longer use their abilities.

Key numbers

  • Effect: vulnerable and suppressed for 4 s
  • Throw it at defender positions that are hard to clear before entering.
  • Shoot right after the bolt: the vulnerable enemy takes more damage and can't react.
  • Save it for a key moment: it costs 300 credits for a single charge.
Key ESignature

Double Tap

1 free charge per round · 1 charge

You focus for 1 s. Then you get a shield that absorbs a burst of damage, you reload faster and you enter a flow state. Your wounded or killed targets leave an orb: shooting it renews the state and the shield.

Key numbers

  • Focus: 1 s
  • Flow state duration: 12 s
  • Reload: +25% speed
  • Start the focus before you clear a tight angle, not during the duel: the focus lasts 1 s.
  • Shoot the orbs as soon as they appear to keep the shield up during the round.
  • Use the shield against a high-damage weapon, like the Operator, to leave cover.
Key XUltimate

Kill Contract

7 ultimate points

A column of energy pulls Iso and the first enemy it hits into an interdimensional arena for a duel to the death. The duel is played with guns and aim.

Key numbers

  • Setup: 2.9 s
  • Duration: 13 s
  • Target an enemy who dominates an angle or a player who is blocking you, not a random player.
  • Cast the ultimate only if your team can cover your exit: an enemy can wait for you.

Strengths

  • The Double Tap shield absorbs a burst, which lets you win a duel that would have been lost on the first bullet.
  • Undercut passes through walls and suppresses whoever it hits, which is useful for clearing positions without entering them.
  • The Contingency wall stops bullets and gives you cover to advance on a site or a lane.
  • The ultimate isolates a single enemy: you remove an Operator or a key player without a team fight.

Weaknesses

  • Almost everything is settled by aim: without good aim, the shield and the ultimate aren't enough.
  • His kit covers tight spaces well but loses value on large open areas.
  • Undercut costs 300 credits for a single charge, which weighs on your gun purchase.
  • During the ultimate you leave the match: your team plays at a disadvantage and an enemy can wait for you on your return.

Tips

  1. Activate Double Tap before the first duel, not during: the focus lasts 1 s.
  2. Save the shield for a dangerous opponent, like an Operator or a high-damage weapon.
  3. Train the flick on stationary targets and precise tracking: the ultimate is a pure aim duel.
  4. Combine the wall and Undercut to step out on a suppressed enemy without taking a bullet.
  5. Choose your ultimate target before casting the column and plan a return with your team.

The aim to train

The Road2Radiant benchmark subcategories that matter most here.

  • Static

    Clicking on static targets

    Iso's duels are won on the first shot: the flick on a stationary target decides the fight after your shield.

    Drills to improve
  • Precise

    Smooth precision tracking

    In the arena or after Undercut, you have to keep your crosshair on the head of a specific enemy: precise tracking matters.
