Every gacha player has run into this classic dilemma: after pulling enough copies to get your frequently used 4-star character to E6, should you prioritize investing in that fully eidolon’ed 4-star, or dump all your resources into a brand new E0 5-star? The truth is, there’s no one-size-fits-all answer to which is stronger. You have to analyze multiple factors like character role, content you’re facing, and upgrade cost. In this guide, we’ll compare the power level of E6 4-stars vs E0 5-stars in Honkai: Star Rail, and share clear building recommendations for new and veteran players alike.
E6 4-Star vs E0 5-Star: Core Strength Comparisons
Damage Output and Utility Comparison
In most cases, the damage and utility of an E6 4-star can match, or even outperform, many E0 5-stars. Getting to E6 unlocks all of a 4-star’s eidolon bonuses, and most 4-stars tie their core power boosts to their final eidolon. Whether you’re looking at a damage dealer or support, the damage boosts and utility improvements from E6 almost always make up for the lower base stats 4-stars naturally have compared to 5-stars.
Of course, this rule doesn’t apply to top-tier meta 5-stars that are considered S-tier in every patch. Even at E0, these top 5-stars have fully complete kits and incredible general utility, so your overall gameplay experience will still be better with them than most E6 4-stars. After all, 5-stars can already use their full core power at E0, and don’t need eidolons to unlock their full strength.
Upgrade Cost Comparison
Getting an E6 4-star is far easier than getting an E6 5-star. Most E6 4-stars are pulled for free while you’re pulling for limited 5-stars, so you don’t need to spend extra money chasing additional copies. The material requirements for leveling and building a 4-star are almost identical to what you need for a 5-star, but if you already have the required materials stockpiled, building an E6 4-star you already have is far easier than starting from scratch with a brand new 5-star.
On the other hand, while an E0 5-star comes with guaranteed base strength, it’s hard for them to reach their full potential if you don’t have a matching 5-star light cone and top-tier relics. That means your early-game investment cost is actually much higher for a new E0 5-star.
Building Recommendations By Character Role
Main Damage Dealer (Main DPS) Role
If you don’t have a fully built main DPS yet, and you have both an E6 4-star DPS and an E0 5-star DPS, your first priority should be looking at general utility and long-term value: if the E0 5-star is a meta main DPS in the current patch, has a complete kit that fits into multiple team compositions, you should prioritize building them even at E0, since they’ll hold their value much longer long-term. If your E0 5-star is a main DPS that requires a very specific team setup that you can’t put together right now, and your E6 4-star works well in most teams, you can build the E6 4-star first as a solid temporary option, then level up the 5-star later when you have the resources.
The truth is, many properly built E6 4-star DPS can easily clear even high-difficulty content, and they hold their own against E0 5-stars. You don’t have to blindly follow the idea that you always need to build 5-stars first.
Support and Utility Roles
Support characters get a huge amount of their power from the utility upgrades that eidolons provide. Most E6 4-star supports are far more useful than E0 5-star supports. They can provide more consistent damage buffs and crowd control, and often even contribute off-field damage on top of their core role, making them incredibly high value for your investment.
If you’re stuck choosing between these two for a support slot, we recommend just prioritizing the E6 4-star support directly. Don’t waste resources building a 5-star support that hasn’t unlocked their eidolon bonuses yet.
Common Myths Debunked
A lot of players hold onto the myth that “5-stars are always stronger than 4-stars”. But when you’re comparing an E6 4-star to an E0 5-star, this idea is completely wrong. Many 4-stars have very specialized kit designs that make them far more useful at E6 than an E0 5-star, especially for free-to-play or low-spend players. A well-built E6 4-star that you’ve had for a while is often the real core of your team, and will help you clear story content and high-difficulty challenges far better than an E0 5-star that you can’t invest in fully.
That said, this doesn’t mean E0 5-stars are always worse than E6 4-stars. Top-tier meta 5-stars still outperform most E6 4-stars even at E0. The key is to make your decision based on your current team composition and how many resources you have available to set your building priority.
At the end of the day, there’s no absolute winner between E6 4-stars and E0 5-stars. For free-to-play and low-spend players, getting the most out of your well-built E6 4-stars will give you a fantastic gameplay experience, and you don’t have to waste your precious limited resources forcing yourself to level an E0 5-star right away. If you’re a higher-spend player, you can easily build both, and swap between them to match the mechanics of different stages to get the best possible results.
