If you decide to advance Han Semi, the first advancement provides the best cost-effectiveness, adding a powerful buff that increases critical hit rate, critical hit damage, and power gauge recovery for the team.

Han Semi performs her core functions effectively even without advancements, so there’s no need to rush her advancement.

While the third breakthrough grants an immortality buff, it's not particularly meaningful since if the character is dying, the battle is likely already lost.

1st Advancement (Recommended):

Upon using her Ultimate, Han Semi applies Sharp Breath to the team. Sharp Breath increases critical hit rate and critical hit damage by 1% per second (up to 10%) and charges 1% of the power gauge per second. This effect lasts for 20 seconds.

2nd Advancement:

Increases user’s HP by 10%.

3rd Advancement:

When Golden Meadow (E skill) is active, allies within the area gain an immortality effect for 2 seconds upon death. After the immortality ends, they recover 30% of Han Semi's max HP. This effect can only trigger once per battle.

4th Advancement:

Increases the Wind attribute damage dealt by the entire team by 10%.

5th Advancement:

When Han Semi tags out, she applies Natural Unity to the team, increasing attack power by 10% and Wind attribute damage by 20% for 25 seconds.
