Honkai Star Rail 3.6 Pull Phainon or Save for Aglaea

★

Core problem: Spend limited jades on one strong Amphoreus DPS without bricking your account on an expensive kit you cannot support. Community consensus is consistent: decide based on the supports you already own and how much vertical investment you are willing to do, not raw who is stronger.

1Inventory Your Current Harmonies and Energy Batteries

Check these first because they change the answer immediately:

1
Do you have Sunday?
2
Do you have HuoHuo or Tingyun plus Robin, Bronya, or RMC?

Aglaea's 350 energy cost is the number one complaint. Without an energy battery or her E1 she feels incomplete and her damage outside Ultimate drops hard. Sunday covers energy, 100 percent action advance, and crit buffs at once. Players repeatedly say E0 Aglaea without Sunday or E1 is half the unit.

Phainon has a higher floor. Players report he still low-cycles with Bronya plus RMC plus Tingyun or Gallagher even before his later supports. He does not demand Sunday as desperately on release.

Action: If you already have Sunday plus at least one energy character, Aglaea becomes much cheaper to make work. If you have almost no limited Harmonies, Phainon is the safer first pull.

2Decide Your Investment Budget (E0 vs E1)

Aglaea E0 E1

E0: Playable but energy gaps hurt. You will want Sunday or HuoHuo.

E1: Solves most energy problems and removes a lot of teammate restrictions. Many Aglaea mains call E1 higher priority than her signature LC or even Sunday if you only care about playing her.

She is described as a luxury always-your-turn DPS that shines in fast MoC and 0-cycle attempts once invested.

Phainon E0

E0: Strong with free or 4-star supports.

Later vertical investment (E2, Cerydra, etc.) raises his ceiling, but he does not require it to function on release.

Players note he sells the I'm the boss now fantasy even at low investment.

2How to Choose

1
Like Aglaea's design and extra-turn gameplay plus you can go for E1 or already have Sunday: pull or save for her.
2
Want a reliable new Destruction DPS that works immediately with what you have: pull Phainon.
3
Low jade count and cannot afford E1 plus Sunday: skip Aglaea or wait for a later rerun.

3Check Team Conflicts

Both characters like Sunday. If you only have one copy and plan to run two teams in MoC, PF, or AS, you will have to split or rotate him. Players who already main Mydei, Castorice, or another Sunday user often recommend against adding Aglaea unless they really like her. Phainon can more easily use Bronya plus RMC as substitutes.

Quick Decision Flowchart

1
Already have Sunday plus energy battery? Aglaea is viable even at E0. E1 makes her excellent.
2
Almost no limited supports? Phainon first.
3
Only enough jades for one E0 and you like both? Phainon. Higher floor, less teammate tax.
4
You just really like Aglaea's animations and turn-spam playstyle? Save or pull her and plan for E1.

Common Mistakes

!
Pulling E0 Aglaea with no energy support and expecting her to feel like the showcases. Community posts repeatedly warn this feels bad.
!
Treating either as a must-pull meta slave pick. Multiple threads note 3.x DPS will drop later. Pull the one whose gameplay you actually enjoy.
!
Ignoring E1 value on Aglaea and dumping everything into her LC first. E1 is called the bigger QoL jump.
!
Assuming Phainon will stay F2P-friendly forever. Later supports still improve him. Plan accordingly if you want his premium team.
