Understanding the Star Upgrade System for Generals
In most mobile strategy games that feature a general system with red stars, you collect duplicates of a hero to upgrade their star level. The basic mechanic is straightforward: every time you obtain a copy of a general you already own, it converts into star fragments or duplicate currency. Those fragments are then spent at the hero screen to increase the red star count. Reaching 5 red stars is usually a significant milestone because it unlocks a large power spike compared to lower star levels. For most popular titles using this system, reaching 5 red stars requires a total of approximately 20 to 25 duplicate copies. The exact number depends on the formula your game uses. One common structure charges 5 copies per star level. That means 5 copies to go from 0 to 1 star, 5 more to reach 2 stars, and so on until 25 total copies lands you at 5 red stars. Another common formula is progressive: the first star costs 1 copy, the second costs 3, the third costs 5, the fourth costs 7, and the fifth costs 9. That adds up to 25 total copies. A third variant, seen in some games, requires 10 copies per star level, bringing the total to 50. Your game's specific formula will determine the final number. I found this out the hard way with one of my main generals. I assumed the cost was a flat rate per star and started saving aggressively, only to discover midway through that each star level scaled up significantly. By the time I hit star 3, I was short by nearly half of what I actually needed. I ended up having to completely change my accumulation strategy and focus on specific modes that drop hero fragments more reliably. Once I identified which game modes gave the best rates, it took me about three weeks of daily play to collect the remaining copies I needed.
How the Upgrade Process Actually Works
You do not simply hand in copies one at a time and watch the star meter fill. Most games convert duplicates into a shard currency. When you pull a duplicate, it automatically becomes shards worth a certain fraction of a full star upgrade. You then manually spend those shards at the general's screen to push the star level up. Some games also include a direct one-to-one conversion at higher star tiers, so each duplicate becomes one star fragment instead of a fraction. Understanding which conversion model your game uses matters a lot for planning your copy hoard. The star upgrade screen usually shows a progress bar filled with fragments. The bar gets wider and harder to fill as the star level increases. This is intentional design to slow you down at higher tiers. You will notice the cost jumps are not always linear. Some games use a logarithmic curve, which means stars 4 and 5 become dramatically more expensive than stars 1 through 3 combined. If you are working toward 5 red stars, expect the last two star levels to consume the majority of your collected duplicates.
Where to Find the Copies
Duplicate copies come from several sources. The primary one is the hero summon system. Pulling from the banner gives you random heroes, and a portion of those pulls will be duplicates of generals you already have. Banner rates vary by game, so check the published drop rates. Some games guarantee a duplicate of a specific general after a certain number of pulls, which can be useful for targeted grinding. Beyond summoning, there are usually daily and weekly activities that reward hero fragments. These include story modes, arena matches, guild activities, and special event missions. In many cases, the fragment rewards from activities are more consistent than relying on the gacha system alone. I recommend tracking which activity gives the best fragment yield and prioritizing it. One player I know stopped pulling on banners entirely and focused exclusively on the event mission track, which let them max out a general to 5 red stars roughly twice as fast. Sometimes games also offer duplicate exchange shops. These shops let you trade excess duplicate copies or fragments for specific hero shards. If a general is your priority, check whether an exchange option exists. Converting useless duplicates into the shards you actually need can be a major shortcut.

Common Pitfalls to Avoid
The biggest mistake players make is spreading their duplicates across too many generals. It is tempting to upgrade several heroes in parallel, but star upgrades scale in cost, and splitting your copies means every hero stays weak for longer. Focusing on one general at a time is almost always the faster path to 5 red stars. You will also waste time and resources if you upgrade a general that you do not plan to use in your main team composition. Another frequent error is ignoring fragment expiration events. Some games run limited-time events that increase fragment drop rates or offer bonus shards. If you are grinding toward 5 red stars, timing your accumulation around these events can cut the process significantly. I missed one of these events once because I was not checking the news tab, and it set my progress back by about two weeks of normal grinding.
Advanced Nuances Most Beginners Miss
Star upgrades are not the only thing that matters for general strength. Equipment, skill trees, and level matter just as much, sometimes more. A 5-star general at a low level will underperform a 3-star general who is fully leveled and well-equipped. Do not neglect the other upgrade paths while chasing star levels. The star system provides percentage boosts to base stats and unlocks skill tiers, but raw level and gear contribute heavily to combat effectiveness throughout most of the game. Some games also implement a star cap or soft cap mechanic. Certain content may become inaccessible if you push a general beyond a specific star level while other parts of your roster lag behind. The game might lock some raids or PvP tiers behind average army star levels. Before you invest all your copies into a single general, check whether the game enforces any balance rules across your team. Pushing one hero too far can sometimes create a bottleneck rather than solving one.
Estimating the Time Investment
Assuming the common progressive formula totaling 25 copies, the time required depends heavily on your daily copy acquisition rate. If you average 2 to 3 duplicate copies per day from summons and events, reaching 5 red stars will take roughly 8 to 12 days of consistent play. Players who invest heavily in the gacha system or who participate in fragment events can accelerate this to under a week. Players on a casual schedule may take several weeks. The real bottleneck is rarely the total number of copies. It is the consistency of daily acquisition. Some days you will pull nothing but duplicates of generals you already have at full star. Other days you will go long stretches without a single useful duplicate. Managing your expectations around this variance is important. Do not get discouraged by dry streaks. They are normal and happen to everyone. If you want the most efficient path to 5 red stars, pick your target general, monitor the summon banners for any rate-up or bonus events, focus your fragment spending on that single hero, and avoid upgrading other generals until your target is complete. The system rewards focus. The costs are predictable enough that you can plan your copy hoard and estimate when you will reach that milestone. Just make sure you verify your game's exact formula before you commit to a grinding schedule.
