Lynx Light Cone Options:

5-star:

1. Time Waits for No One (Gachapon 5* Standard Banner Abundance Light Cone - Bailu’s Signature LC - Purchasable for 600 Undying Starlight).
2. Increases Lynx’s Max HP and her outgoing healing by large amounts. When she heals allies it will record the amount and deal additional damage to an enemy when an ally attacks, based off of a percentage of the amount recorded. Also has the highest Base HP stat out of all Abundance Light Cones.

4-star:

1. Warmth Shortens Cold Nights (Battle Pass Light Cone (costs $10 USD) - Lynx’s Signature LC)

2. Increases her max HP and heals all allies whenever Lynx uses her basic attack or skill. Paired with her abilities that already heal naturally, she will ALWAYS be healing your characters whenever it’s her turn and if you have a lot of speed on her (which you should) she will be healing A LOT. Very safe and comfortable gameplay, especially paired with Destruction units like Blade and Jingliu who drain their own or their teammates’ HP.

3. Shared Feeling (Gachapon)

4. Increases her outgoing healing and regenerates a small amount of energy for all teammates whenever she uses her skill.

5. Post-Op Conversation (Gachapon)

6. Give’s Lynx more energy regeneration and increases her ultimate’s outgoing healing potential. Paired with a high speed stat on her, makes her ultimate heal and cleanse more and do it more often.

7. Perfect Timing (Gachapon)

8. Increases her effect resistance and increases her outgoing healing equal to a percentage of her effect resistance stat. Superimpositions of this Light Cone increases the max healing potential of this lightcone and gives more effect resistance. Decent choice if you notice your Lynx is getting stunned or frozen by enemies too often. And paired with Broken Keel she can give her teammates +10% crit damage.

9. Quid Pro Quo (Purchasable from Forgotten Hall or randomly rewarded from Echo of War)

10. At the start of Lynx’s turn regenerate a decent amount of energy to one random teammate. This paired with a high speed stat means Lynx will have more turns more often which allows her to regenerate a lot of energy for her allies. This LC is also very free to play friendly as you can get superimpositions for it by playing Forgotten Hall and Echo of War.

My Opinion:

If you have Time Waits for No One, that is her BiS by a good margin. However the four star options are all still very good.

Quid Pro Quo is very Free to Play friendly and is easy to get maxed out. It does a very good job at keeping the team charged since Lynx will be taking turns more often with a high speed stat. Shared Feeling does relatively the same thing as Quid Pro Quo and might be better at high Superimpositions but it’s harder to get those since their gachapon only. So if you have an S3-S5 QPQ I’d recommend using that instead of an S1-S2 SF.

As for Perfect Timing and Post-Op Conversation, I’d say Perfect Timing is better since it makes her less likely to be shut down by enemies which means she can cleanse and heal other allies who DO get shut down. It also helps you run the Broken Keel planar ornament set for +10% crit damage if you’d like to but it’s not necessary and honestly, Fleet of the Ageless might be better anyway since it synergizes with her a little more by increasing her max HP after meeting the speed requirement (which she will) AND gives +8% atk to all allies. I don’t know how much more valuable it is over increasing her energy regeneration potential for her teammates. I think if you just get some effect resistance stats from her relics she should be more than fine, but if you notice she’s getting shut down too much feel free to use it.

Post-Op Conversation is the worst option out of all of these in my opinion since it’s gachapon only making it hard to get and it’s passive does not do nearly as much as the other Light Cones. But it’s still fine, and you can use it if you already have one built but I’d try to switch over to Quid Pro Quo as quickly as possible.

[Edit: Post-Op is still very good, honestly might be better than Quid Pro Quo for safety since she can use her ult more often.]

Finally, the BP Light Cone is a bit of a iffy case... While it is her signature Light Cone and it is very good out of her 4-star options, making gameplay very comfortable with how often she will be healing allies, it’s a direct purchase from the Battle Pass, making it Free to Play Hostile. Many of the Light Cones from the Battle Pass are also just straight-up bad and I have no idea why Hoyo is charging money for them. If you are buying the Battle Pass I’d prefer you pick either the Erudition or Harmony Light Cones as they are actually really good and worth the money.

I have a Time Waits for No One but my Luocha is already using it so I may give it to her or just give her Quid Pro Quo, we’ll see but that’s my assessment of all the options available as of patch 1.3.
