Now that Feihan has left the Battle Pass shop, players following 12BET Mobile guides can exchange Crystal Amber directly for this hero. Recent events have given players plenty of opportunities to collect Crystal Amber, so many should already have enough to unlock her. The next question is how to develop Feihan properly and get the most out of her abilities.
For equipment, the most straightforward setup is 20 Butterfly Transformation and 5 Mirror Shadow. Mirror Shadow can be placed in any slot, so there is no strict positional requirement. For the Universal Flow setup, use 1 Mechanism and 4 Glory. If you cannot complete the four-piece Glory setup, Grimoire can serve as a temporary replacement. At Flow Tier 6, Infinite Bunny is the recommended choice. Compared with the Great White Encore route, Infinite Bunny does not require strict skill timing and also delivers higher damage, making it the current mainstream option.
At Flow Tier 10, choose Frozen Follow-Up. Once this route is activated, the combo is easy to remember: cast Ice Tornado first, then immediately use Skill 3 to produce a powerful burst of damage. Rapid Ice Light is not recommended because its automatically fired Frost Beam can interfere with the damage efficiency of Skill 2.
As players refine their Feihan setup through 12BET Mobile, skill investment should focus on fully upgrading Flow Skill Mastery first. Ultimate Burst can receive additional points when spare resources are available, while Foundation Training can be skipped. Her weapon should be the red-tier weapon and upgraded to the maximum level, since this remains one of the most important parts of the build.
Rune choices change slightly depending on the support character. When Feihan is paired with Master Luban, the recommended setup is 6 Conflict, 6 Echo and 6 Prosperity. This combination helps cover the missing critical rate while also increasing overall Flow strength.
When using other supports, a more balanced setup is 5 Conflict, 1 Peerless, 6 Revival and 6 Reincarnation. This configuration keeps the core attributes more evenly distributed. For the Spirit companion, King Laifu is the preferred option because it provides a substantial increase to Flow Skill damage.
Master Luban remains the most highly recommended support for Feihan because he can provide shields together with a strong critical damage bonus. Players who prefer a more team-oriented composition can also consider Wang Zhaojun or Longya. Wang Zhaojun offers greater room for error, while Longya improves the entire team’s damage output. However, Longya’s bonus can be diluted because it overlaps with several other damage multipliers, so he is better treated as an alternative rather than the first choice.
Sun Bin can also work as a secondary damage dealer. His damage is far from weak, but he requires more careful execution and stricter timing between abilities, making the lineup harder to manage. For players who enjoy more technical rotations, however, he remains a viable option.
To complete the build, players checking 12BET Mobile can use the Xichun Lianyu Roll together with Qinghui Guanmeng Soup for additional critical rate. Those with enough resources can also use two consumable buffs at the same time to push Feihan’s maximum damage potential even higher. With the right equipment, Flow choices, runes, support and consumables in place, the build can bring out her strongest performance without making the rotation unnecessarily complicated.
