G: Here’s what you get for maxing out (fully completing) your relationships with Dusa and Hypnos in Hades on PS5 (this is the same across platforms since the game content is consistent):

---

🪄 Dusa – Benefits of Maxing Her Relationship

1. Companion: Fidi

• Once you complete Dusa’s affinity and gift her Ambrosia, she gives Zagreus the Companion Fidi.
• Fidi’s Effect: When summoned in combat, Dusa appears and fires petrifying shots that deal damage and briefly stun enemies for up to about 30 s. You can use this Companion once per encounter, with additional uses per run unlocked by upgrading it with more Ambrosia. citeturn1search0turn1search4

2. Adds to Story and Dialogue

• Maxing Dusa’s affinity unlocks more personal story beats and deeper conversations between her and Zagreus. citeturn1search16

3. Keepsake and Cosmetic Flourishes

• Giving Dusa Nectar earlier on gives you her keepsake item, which you can equip before runs (but it doesn’t provide combat bonuses by itself). Fully maxing out just provides more flavor and narrative payoff. citeturn0search0

4. A Unique Platonic “Bond Forged” Ending

• Dusa doesn’t enter a romantic relationship with Zagreus the way some others can. After the final Ambrosia gift, she explains she cares deeply for him but not in a romantic way—they remain eternal friends. citeturn1search16

😴 Hypnos – What Happens When You Max His Relationship

1. No Companion Directly from Hypnos

• Unlike Dusa, Hypnos doesn’t grant a Companion or combat ability as a reward for maxing out his affinity. Most NPC relationships in Hades provide mainly narrative benefits. citeturn0search0

2. More Dialogue and Character Development

• Maxing Hypnos leads to expanded conversations with him and with related characters like Thanatos as part of his relationship storyline—more insight into Hypnos’s personality, struggles, and his friendship with Zagreus. citeturn1search1

3. Narrative Flavor and Worldbuilding

• Deepening your bond with Hypnos enriches the game’s story and his character arc as the Incarnation of Sleep, but there’s no gameplay reward (like a Companion or stat bonus) tied to it. citeturn0search2

📌 General Notes About Maxed Relationships

• Most NPC affinities are mainly narrative: maxing out relationships gives more story, dialogue, and cosmetic treats (like an icon on keepsakes), but only some characters provide gameplay companions. citeturn0search2
• Characters that give Companions include Dusa (Fidi), Megaera, Skelly, Sisyphus, Thanatos, and Achilles — but not Hypnos. citeturn0search2

Summary

Character	Gameplay Reward	Story/Dialogue	Companion
Dusa	Yes — Fidi summon	Yes	✔️ Fidi companion
Hypnos	No gameplay bonus	Yes	❌

If you want, I can also tell you how to complete Dusa’s favor requirements and unlock her affinity earlier (it requires remodeling the House lounge first).

G: Short answer: No — outside of the few Companion summons and the narrative/keepsake stuff, maxing out relationships in Hades (PS5 and all versions) does not give you any additional gameplay benefits such as stat boosts, boon effects, or combat advantages. The main exceptions are the Companion rewards (like Fidi from Dusa), which you already know about. citeturn0search0turn0search2

🧠 What Maxing Out Relationships Does Give You

1. Narrative/Story Content
Maxed relationships unlock more character dialogue, story scenes, and deeper lore about the characters you bond with. Players often treat this as one of the best reasons to pursue affinities. citeturn0search0

2. Keepsake Icons / Visual Indicators
Once you fully max a relationship, you get a little icon next to that character’s keepsake in the selection menu, just to show you’ve “Forged a Bond” with them. This is purely cosmetic. citeturn0search2

3. Companions (Gameplay Effect)
Only some characters give you Companion items when you hit certain affinity levels. These do provide gameplay utility because they let you summon an attack or ability in runs. Dusa’s Fidi is one example. citeturn0search0

❗ What It Doesn’t Do

• Maxing relationships doesn’t grant stat boosts (like more damage, defense, or HP). citeturn0search2
• It doesn’t increase boon rarity or improve boon chances. There’s no documented mechanic tying affinity levels to your actual combat performance or anything affecting how runs play out beyond the companions. citeturn0search2
• Outside of companions and story beats, there are no special gameplay bonuses just from maxing someone’s hearts.

📌 Special Case: End-of-Game / Prophecies

While there’s no direct gameplay buff for maxing individual character relationships, some prophecies or epilogue conditions in the game’s achievement/progression system require you to max certain bonds (especially with gods) before you can unlock those milestones. That’s more of a meta progression requirement rather than a raw in-run benefit. citeturn0search3

Summary:
Aside from unlocking Companions from certain characters (which do have combat utility), maxing out a relationship in Hades is primarily about story, dialogue, and cosmetic keepsake markers — not direct gameplay advantages. citeturn0search0turn0search2
