I have a player whose character wants to kill the gods. When this character was a small child some of the gods came and killed her clan. One of the gods had pity on her and revived her as an assimar. Now she seeks revenge and is heading to Candlekeep to gain knowledge on how to kill the gods.
So with the current rules can you kill the gods?
Are there weapons or armor you need to have to kill the gods?
Deity death is possible and it's part of the lore, it's just very difficult. The Raven Queen is said to have become a god by killing the previous god of death. There are also floating god-corpses in the astral plane. Consider Auril, from Rime of the Frost Maiden. She can be defeated in combat, but she'll eventually reform elsewhere. What a character would need to accomplish before killing a god permanently would be up to a DM, but should require a very dangerous set of quests that would see the characters facing worshipers of the god in question.
Yea I've been looking around and trying to figure this out but so far what I have run into is back in 3e you had to be lvl 25 and have the support of another god to kill a god. With 5e you can only go up to lvl 20 and this character is trying to find a way to kill all the gods. So I'm not sure how she could achieve that with the current rules. And yes I agree it would be a set of quests and facing worshipers.
As state godkilling isn't in the rules but many things can happen in D&D that aren't in the rules.
Gods don't really have stats. Even Auril, you don't really kill her I think, so much as defeat her and get her to change her ways. Beyond that I know Mephistopheles and a few other Demon Lords and Arch Devils are statted, and then beyond that you got Tiamat and Bahamut but those stats are explicitly "aspects" defeating them doesn't kill them.
So you don't have the mechanics to simply kill gods in conventional within the rules D&D combat. So rather than resolve the desire to kill gods through the available mechanics, you'll have to build a different device. And that's all imagination.

Maybe catch Thor Love and Thunder. Especially if the PC is question is named Gor. Therein you have a "godslaying" weapon available, you also have the idea of a a place/entity that predates the gods which can also remove the gods from existence. There are a lot of possibilities between that sword and eternity for a DM to devise a way to deitycide.
Well we have an example of a god in the Monster Manual- Tiamat. Tiamat is a legitimate god (or goddess) and is a level 30 CR that can be fought and “killed” in combat. Whether or not she actually dies is up to you the DM, in standard Forgotten Realms lore her essence would return to her home plane and slowly reform over the centuries.
Using Tiamat as a template, you can homebrew other CR30 gods of roughly equivalent power. Maybe brows some existing ones in the homebrew section first.

She doesn't change her ways so much as just act like a Saturday Morning Cartoon villain who gives up once beaten by the hero and never uses the same plan twice.
The mechanics of it are almost completely unsupported in 5e. In previous editions, it was found that the moment you gave a God a stat-block, then players would just figure out how to kill them and treat them like any other creature. So in order to have the Gods feel more "Godly", they're largely left without stats and with fairly loose rules on what, exactly, they can or can't do. Even the Gods that are statted, like Tiamat, have language in their statblock clarifying that what you're actually fighting is an Avatar, and their true form cannot be destroyed through conventional methods.
So, for this to work, you basically need to get into homebrewing. I think it's a good hook for an adventure... evil Gods are vanquished in D&D by high level parties all the time. I do think it would be best to include an object or force that is very difficult to find that is key. I think a God-slaying weapon is a good hook... it gives the players something tangible to reach toward.

You can do this, but as you note what you're citing is not actually a Tiamat that would be "killed" in the OP's godslaying sense.
First off, Tiamat isn't in the Monster Manual. The CR 30 Tiamat is in Fizban's and is described as an Aspect of Tiamat. It's not "Tiamat" but a manifestation of Tiamat on a a plane of existence upon which she is encroaching, usually the Prime Material. If this CR30 Aspect is defeated, she's not dead, just vanquished from that plane. That is not what the OP godslayer conceit is going for.
Again, you can handwave it and use Aspects of Tiamat and Bahamut and Archfiends and Auril to create "gods" to be "killed" in the game. However, if you're being faithful to the lore and mechanics of 5e, an actual god is at least a few more increments in power above a CR 30 representation of that god. So the question becomes, how do you kill something whom you're only able to defeat as a projected manifestation? The answer isn't in the existing rules, so it's a homebrew lore solution as to whether it can even be done, and if it can be done, how can it be done.
In my game, Tiamat's "death" is the likely climax. Though even there, the PC would not so much be killing Tiamat so much as repairing Tiamat from injuries that made her what she is in common lore (lot of homebrew setting backstory here). To do this task, the part need texts from The Library of Hated Lore (a location mentioned in an old Planescape adventure), the Flail of Tiamat (which was actually used by agents of Bahamut to scourge what was once an integral unifed headed dragon into her present five headed "dissolute" form), and nine dragon orb type artifacts (one for each of her heads, plus four for orange, yellow, indigo and violet and bring the archetypes of these "lost chromatics" to be reintegrated). This act in my game wouldn't just transform Tiamat but would be a literally apocalyptic event for the rest of the multiverse (since in this game we lean on Fizban's lore indicating Dragons and their ordering is integral to the arrangement of reality). For a "pantheon killer" game it might be interesting to have a cycle of apocalypses as the party dismantle the architecture of their universe, depending how integrated gods are into it.

There's a different CR 30 Tiamat that showed up in Hoard of the Dragon Queen and Descent Into Avernus. But that version is also not Tiamat's full power and killing it just causes her to reform in Avernus after a while.
The closest thing we've seen to actual rules for killing a god in 5E is from Rime of the Frost Maiden, where you can kill Auril's physical body but she'll reform again on the next winter solstace unless you can manage to kill every worshiper she has in the multiverse before then.

"Canon" is what's factual to D&D lore. "Cannon" is what you're going to be shot with if you keep getting the word wrong.
Just beating them in a fight and destroying their current incarnation, that's relatively easy. With divine assistance or powerful artifacts most gods can be " killed" in the same way a devil can be forcing them to reform else where at a later date. The challenge is making them stay dead. In lore deities die but they don't stay dead unless for some reason they lose their portfolio. That can be:
Being completely forgotten ( all followers die)
Having their role taken by another god
Everything they have power over disappearing. For example a god of a specific instrument might permanently die if all of that instrument are destroyed.
Even in these cases gods can be resurrected by sufficiently powerful gods or magic but that will put them down for a while.

Yeah it's a pretty easy inference that the Hoard of the Dragon Queen Tiamat is an aspect being brought into Faerun; and in Descent I'm pretty sure she or Arkan literally say she remains in her prison but will send forth this manifestation or avatar for the grand finale.
I guess Auril does give players a very dark option for a godkiller campaign. Kill "all the gods" and then "kill all their followers". I mean there's space for that in some Sword and Sorcery and Dark Fantasy, though it's not what a player inspired by say the God of War franchise is looking for.
In older FR lore, I remember there was a big novel and adventure selling event that involved what are in present lore the Dead Three. I forget whether they rose to power as adventurers who became gods by killing their predecessor and taking their domain (and presumably a number of their worshippers, though I imagine schisms and civil wars within the faiths and cults happened) or they were the gods the adventures killed. Bane and someome named I think Cyric(?) had big arcs in those books, I think.

The Dead Three were Bane (god of tyranny), Bhaal (god of murder), and Myrkul (god of the dead). They were originally mortals who sought godhood and achieved it by finding Jergal, the previous god of the dead who'd become bored with his role and gave each of them a portion of his power. They became known as the Dead Three after they were all slain during the Time of Troubles (Bane and Torm killed each other, Myrkul was killed by the adventurer Midnight, and Bhaal was killed by Cyric). All three of them eventually ended up returning to life though different means- the first Baldur's Gate computer game is broad-strokes canon regarding Bhaal.

"Canon" is what's factual to D&D lore. "Cannon" is what you're going to be shot with if you keep getting the word wrong.
In my opinion the Tiamat in Hoard of the dragon queen is actually Tiamat as allot of the plot and lore is about her escaping Avernus more than it is invading the material plane. At the very least it's enough of Tiamat that several powerful gods and devils conspire to either assist or prevent her plan based on how her presence or absence will effect Avernus and the book treats her success as her leaving the hells. It is her physical body it's just that gods powers are not fully encapsulated in their bodies so their stat block does not necessarily represent their full power. Remember gods also have artifacts, clerics, divine realms and creations which are part of their power. Strength for a god does not necessarily mean just hitting something harder with their axe and the strength of their bodies matter little when they just resurrect on death.
I had a character who wanted to answer this question. She came up with... a dagger made of residuum, imbued with the blood of an immortal, and tempered with anti-magic might be able to cut immortal flesh.
Can you kill a diety in a D&D world? The answer is completely up to the DM. The players don't have any say in whether this is possible or not for some or all or none of the gods in any particular game world. In the D&D lore from previous editions, there have been several examples of gods being "killed" or disappearing or possibly dying for a variety of plot reasons but whether that applies at all in any particular game world is entirely up to the DM.
So if you are the DM - decide whether it is possible in your world. If you are a player, ask the DM if it is possible in their world.
P.S. In any case, gods would appear to be vastly more powerful than characters - they have worshippers and depending on the lore you choose for your world it could be that a god will never actually die if they still have worshippers feeding them power. However, this is all up to the DM.
In Rime of the Frost Maiden, you can kill Auril but she reconstitutes over a period of time. You can't actually kill her.
In Rise of Tiamat, I think you can kill the avatar but I'm not sure if you can actually kill the god.
Finally, consider if you have a character that wants to kill the "gods" ... if they are successful and manage to kill even one ... all of the gods will have a vested interest in seeing this upstart mortal dead or enslaved. The mortal would need to be as powerful as one of these beings in order to not only successfully kill them but survive when the gods decide to take action and eliminate the threat.
So after all my research, it seems like to kill a god you have to kill them in their domain (where they are the most powerful) and have the power equal to or greater than them. Then to make sure that they can never revive you have to destroy their body in the Ethereal Plane. There are a few weapons that can kill gods (Godsbane, Jathiman Dagger, Crescent Blade) but over the years there may have lost power or even become cursed. Also, you have to be careful. If you even say a god's name depending on their power that god could watch you for a day up to a year. If you kill a god you have to be able to control the power and take on that god's role and responsibility or a disaster may happen like the spellplague.
