AI Limit Guide | Road Sign Build

A guide for one of the most overpowered builds in AI Limit, the Road Sign build.

Game Guide by Ornstein on May 29, 2025

You’re running a heavy-worker, glass-cannon build that delivers massive lightning damage—probably one of the most powerful builds available. If you avoid silly mistakes (which you’ll see shortly that I made), you can finish Mutated Ursula in almost one go. Keep in mind that this is Cycle Three.

Build Setup

You’re using Road Sign Scales with Strength and Technique. You’ve invested more than you should in Technique—you could reduce that and put more into Health or Vitality—but you prefer a bit more Vitality.

Spirit is at 15 because you need it for Electrification (you could also use Ignition). You’ve also put points into Life to compensate for the lack of defensive Seals. This spread creates a glass-cannon feel, offering high damage at the expense of defense.

Your weapon is maxed out for +400 Lightning Damage to weapon skills and spells, but the real benefit here is the lightning-damage boost and the 60% Conversion increase for a short duration. You’ve chosen the Upgrade Deviation perk to raise your damage further for attacks, spells, and skills.

Fatal Strike is at 30% to capitalize on counters, and you’ve taken Counter Field because you counter often—though you could swap it out if you prefer more mobility. Overall, this setup maximizes damage output, letting you shred bosses quickly.

Build Gameplay vs. Ursula Boss

In your first test runs, you immediately noticed how strong this build is. You’ll want to parry well and capitalize on your Fatal Strike and lightning skills. When Ursula is fully mutated, amplify your damage with Electrification or Ignition as needed, then hit her with a parry-combo rotation.

Even if you make a mistake and have to run away, once you nail that one parry and unleash your combo, you can destroy her before she recovers.

If you miss an initial attack, retreat, reset your spacing, and repeat the parry-combo sequence. Even a single well-timed parry followed by your skill rotation will down her quickly. After she wakes up, you can continue your skills and finish her off before she regains her footing.

Tips

This build balances attack speed so you won’t feel sluggish or miss dodge and block opportunities. Your damage is amplified by Seals and your focus on skill damage, enabling you to drop enemies swiftly and refill your Conversion bar for repeated skill executions.

If you execute a Fatal Strike, you can quickly enter the colored bar and use your skill a second—or even third—time.

Because you’ve sacrificed defense, mistakes can be devastating. If you prefer more survivability, you can swap some points into defense or Vitality or replace Counter Field with another defensive perk.

If you’re consistently landing parries, you might remove Counter Field altogether and invest in higher Conversion to reach your skill thresholds more reliably.

Adjust your armor and perks to match your play style and the fight theme—choose defensive pieces for extra protection, or stick with the thematic look if you value aesthetics. Regardless, this build remains exceptionally powerful and is well worth trying out.
