Vehicle Planning at a Glance

Use these milestones to decide whether you should keep saving wrenches or push the next unlock now.

Hercules unlocks at level 95 with a cumulative total of 1,730 wrenches.

If you are still building your wrench supply, use the Gacha Go Guide to plan the best key and diamond strategy before committing to big vehicle milestones.

For the wider account impact of vehicle progression, use the Power Guide to compare vehicle power against other major upgrade paths.

Expert Modifier Strategy

The Expert Modifier does not activate automatically when you unlock Hercules. You must enable it manually by clicking it in the top-left corner, in the same Modify section where you use wrenches. After unlocking Hercules, the Expert Modifier will glow to show it is available. It activates immediately when you click it. You can delay activation, but be very careful not to click it by mistake, because once enabled, it cannot be deactivated.
Expert Modifier lasts 30 minutes and applies to 100 upgrades only. If you plan to use it right after unlocking Hercules, prepare at least 170k–200k blueprints to be safe. That should cover roughly 100 upgrades (about 20 levels). If you plan to use the Expert Modifier later, use this formula to estimate how many blueprints to save: current vehicle upgrade cost ×130. Example: if your current upgrade cost is 2,000 blueprints, prepare around 260k blueprints.

Tips and Tricks

Unlock the Mia hero as early as you can, build her to 5 stars, and raise her 3rd skill to level 30 to reach her full potential.
Pick up the Advanced Mod License from the License Store when possible. It saves thousands of blueprints early, and later can save hundreds of thousands of blueprints.
Schedule vehicle upgrades for Alliance Duel – Modification Day (Mondays) and during Full Preparedness to maximize returns on golden wrenches and blueprints.

Advanced Mod License

Mia 3rd Skill

Advanced Mod License

Advanced Mod License is a License Store item that reduces blueprint cost on vehicle modification upgrades. It’s most valuable early, but still saves a large amount of blueprints later.

Expert Modifier (Activation & Prep)

Expert Modifier is a time-limited boost you activate manually after unlocking Hercules. It applies to a fixed number of upgrades, so prepare enough blueprints before starting.

Elite modifier / Modification Rating

Elite modifier is the rating tier shown at specific levels. Use the table to find the breakpoint levels and plan your upgrades around those thresholds.

Before Spending Wrenches

Use the table and planner to estimate your next vehicle milestone, then confirm the live Modify screen before spending wrenches or blueprints.
Prepare blueprint value before using Expert Modifier, because the boost is timed and cannot be treated like a normal permanent upgrade.
If your vehicle costs, license value, or event rewards look different in game, follow the live screen first.
