Undead Class: Permanent Buffs on Every Revive — Worth 100 Diamonds?
The Undead costs 100 Diamonds and gains a permanent buff every time a teammate revives you. The five-buff upgrade list, the 30 and 60 revive requirements, how it works solo with Respawn Capsules, why tier lists rank it anywhere from A to C, and an honest verdict.
The Undead is one of the only classes in 99 Nights in the Forest that gets stronger by dying. Every time someone revives you, you keep a buff forever. That is the whole design — and it is also the whole problem, because nobody has to revive you for free.
For 100 Diamonds you start with a Bandage and an Upgrade List — the item that tracks which buffs you have already claimed. The buffs are permanent and they do not repeat, which turns the class into a supply question: how many times will the rest of your group spend a bandage on you this run?

Undead Class at a Glance
| Cost | 100 Diamonds |
| Starting item | 1× Bandage, plus the Upgrade List |
| Type | Revival / scaling |
| Level-up requirement | Be revived 30 times, then 60 times |
| Added in | 2× Gem Weekend + Classes MK III, 11 October 2025 |
| Weakness | Dead weight unless a teammate is carrying bandages |
| Best at | Long team runs where your group already revives you |
| Weakest at | Solo runs — nothing in the kit fires on its own |
The class arrived alongside Beastmaster and the Necromancer, and the same patch moved the taming flutes to the Abandoned Animal Shelter. Two sources — the wiki's patch notes and rblxguide's update log — put it on 11 October 2025. Two others say 10 November 2025, so the date is genuinely unsettled. We flag it rather than pick silently.
Perks by Level
| Level | Perk | Requirement to reach it |
|---|---|---|
| 1 | Gain a permanent bonus every time you are revived | Unlocked on purchase |
| 2 | You can be revived instantly — no wait after death | Be revived 30 times (0/30) |
| 3 | You can move for 8 seconds after death — you cannot attack in that window, and enemy aggro does not follow you | Be revived 60 times (0/60) |
Level 1 is not a perk you activate. It is a passive that only resolves when somebody else spends an item on you. That makes this the most team-dependent class in the cheap tier.
Level 2 is the one that changes how the class feels. After thirty revives, getting put back on your feet no longer costs you the downed timer, and the reset between deaths gets cheap enough to repeat on purpose.
Level 3 is a survival tool, not a damage tool. Eight seconds during which you cannot swing exists so you can step out of the pile that killed you — or walk toward the teammate who is about to revive you. Aggro dropping off during it is what makes the repositioning safe.
The Upgrade List: What You Actually Collect
Each revive grants exactly one buff, drawn at random from a fixed list. Entries on the list do not repeat.
| Buff | What it does | How it plays |
|---|---|---|
| +20 HP | Raises your maximum health | The compounding one — five of these add 100 max HP on top of your base |
| +200 Coins | Cash the moment you come back | The wiki calls this a mediocre payoff; coins stop mattering around night 20 |
| Hunger drains slower | Less food pressure per day | Real value on very long runs, where food becomes the wall |
| Sprint faster | Faster sprinting | The wiki's own top pick — it is the buff that combos with escaping |
| Crock Pot cooks faster | Faster cooking | The dud, and the wiki says so outright |
Why the Crock Pot buff is the dud. Food supply is gated by ingredients, not by how fast the pot runs. The wiki's tip list says aim for the sprint buff and treat a Crock Pot roll as a lucky accident. It is the only cooking-related perk in the game with an explicit "don't chase this" warning attached.
The sprint buff only affects sprinting — not walking speed, not swing speed. The wiki states that plainly, and it matters when you are planning an escape line out of a biome.
Two of the five buffs are rated filler by the wiki itself, and the draw is random. So the honest shape of the class is three good outcomes out of five, awarded one revive at a time, on a timer someone else controls.
The Number Nobody Reconciles: Five Buffs, Sixty Revives
Here is the tension in the class, and we could not find a single source that addresses it.
The upgrade list has five entries, and the wiki states the buffs are non-repeatable — so on the strictest reading, all five are claimed after five revives, and every revive after that grants nothing. The wiki's own framing is that the buffs "stack until all five are unlocked".
But Level 2 needs 30 revives and Level 3 needs 60.
→ Our reading, and we are flagging it as ours: if the five-buff cap is real, the Undead's entire reward ladder is five revives deep, and the remaining fifty-five buys you two utility passives you hardly need. That would make a class advertised as growing stronger with every death stop growing after the fifth one.
The competing reading, from a second guide, is that the buffs stack without limit — same five-item list, no ceiling. That reading makes Level 3's sixty revives coherent, because the last forty would keep paying out something.
We cannot settle it, and we are not going to invent an answer. What both readings agree on is the practical consequence: the counter is what you are grinding, and no source says what the counter pays past the fifth revive.
How to Level It Up
With a team — the normal way. Die, get revived, repeat. The wiki describes the loop without decoration: a teammate carries bandages, the Undead dies somewhere manageable, the teammate revives, the counter moves. It also documents the faster version — bring in a second device or a willing friend, have them pick up the Undead's starting Bandage off the ground to revive you, then restart the loop. The wiki says it runs faster again if that second player is a Medic, or any other class that starts with bandages.
Where the revives come from. Bandages and Medkits are the consumables, so the Undead quietly raises everyone else's demand for them. The wiki's cons list is blunt: the class "need[s] many bandages to be at full potential". If nobody in your group is carrying them, this class runs at maybe a third of its speed.
Solo — the expensive way. The only documented solo route is the Respawn Capsule, and the wiki's own verdict is not recommended because of the cost. The crafting cost ramps per buff: 1, 3, 7, 15 and 31 Cultist Gems for the first through the fifth. That is 57 Cultist Gems in total (our arithmetic on the published figures) for five revives — and the counter above still has to move. Before spending any of them, read how Cultist Gems drop: only the last cultist killed in a fight drops one, which is what caps the whole solo route per run.
Whether a Respawn Capsule revive also counts toward the 0/60 counter is stated nowhere. Treat the solo route as a way to collect the buffs and do not assume it levels the class.
The counter shows no run limit. Class levels appear to persist across runs, which would make 0/60 a lifetime tally rather than a per-run one — but no source says that outright, so treat the pace you will reach as unknown rather than planned around.
Undead vs the Other 100-Diamond Classes
With three cheap picks, the real question is not which one hits hardest. It is who triggers your power.
| Undead | Berserker | Alien | |
|---|---|---|---|
| Trigger | A teammate revives you | Your own first death | Always on |
| Level 1 gives you | A buff for dying badly | Auto-revive once per run | Night vision + a Raygun |
| Team value | Scales with how often you go down | A second life for the whole group | Answers threats at range |
| Solo value | Near zero | High | High |
| Requirement style | Be revived 30, then 60 times | Kill 50, then 150 enemies under 40% HP | Kill 150, then 300 with alien tech |
The full three-way table with per-level detail lives on the Berserker page, which already lists the Undead as the pick for groups that revive each other often.
The short version: Berserker is the cheap class that makes one death free. The Undead is the cheap class that makes every death a transaction. One of those pays out when you are alone, and the other does not.
Is It Worth 100 Diamonds?
Yes, in a group that already carries bandages. If your team is routinely digging you out of a bad night, the Undead turns an expense they were paying anyway into permanent stats — and the sprint buff is the cheapest sprint speed in the game.
Yes, if a Medic is in the lobby. Revives are the engine, and the Medic makes the engine run several times faster for 40 Diamonds. That pairing is the class.
No, if you play solo. Every source that addresses solo play says the same thing. Without a reviver your level-1 perk is an item in your sack and your level-3 perk is eight seconds you cannot act in. Cyborg or Big Game Hunter does what the Undead is trying to do without needing a teammate.
No, if you wanted damage. The Undead grants zero damage. Not one buff on the list increases what you deal. If that is what you came for, buy the Brawler instead.
No, if you are new. This is a class about dying on purpose, which presupposes you already know what a death costs. Buy something that teaches you the map first.
Getting to 100 Diamonds is the real cost either way — see how to farm Diamonds fast, and check active codes before you spend.
Tips That Change How It Feels
Chase the sprint buff, not the Crock Pot one. A mediocre roll costs you a revive that could have been the sprint. The wiki says the same thing from the other direction: if you find yourself aiming at the faster Crock Pot, you have already lost the roll.
Level 3 is not a combat window. You cannot swing in those eight seconds. Use them to leave the pile — not to hit something.
Use the post-death movement to reach your reviver. Aggro drops off during it, which is the whole point. Choose where you die instead of surviving wherever you happened to fall.
Die where the bandages are. A reviver standing ten metres away revives you many more times than one sprinting across the base. Death location is a resource decision.
Do not make this your first class. It demands a team, and a team is the one thing a brand-new player does not yet have.
Stock bandages yourself if nobody else will. The class starts you with a single Bandage, and the wiki notes several are needed to reach full potential.
Pros and Cons
Pros
- The cheapest class in the game that gives a sprint speed buff — the wiki's first pro, and the reason to own it
- Every revive permanently makes the next death less likely to finish you
- Level 2's instant revive is the strongest team-safety tool at this price
- Level 3 can genuinely save a run — eight free seconds of repositioning
- Rewards a group that already plays around reviving, instead of asking them to change
Cons
- Almost useless in solo runs unless you pay for your own revives
- Needs a lot of bandages from the rest of the group
- +200 Coins and faster Crock Pot are, in the wiki's own words, mediocre — two of five rolls are filler
- Very hard to level — thirty revives, then sixty
- The reward structure past five buffs is undocumented, as above
- Nothing it grants increases your damage
Where Sources Disagree
Tier lists span A to C, and the spread is exactly the team/solo line. PCGamesN puts the Undead in A-tier. Pocket Gamer puts it in B-tier, next to the Lumberjack and the Brawler. PC Gamer puts it in C-tier, beside the Camper and the Cook. rblxguide's June 2026 list does not rate it at all. The placement tracks how each list treats solo play — PC Gamer's own caveat is that some classes are great in multiplayer and a disaster alone.
The release date is a tie. 11 October 2025 on the wiki's patch page and on rblxguide versus 10 November 2025 on two other guides. A third source dates the same three classes to March 2026; we discount that because it ties them to a Fairy Biome patch that no other source agrees on. We lead with 11 October 2025 as the better-sourced reading and state the dissent.
Whether the buffs cap at five or stack forever — the wiki says one thing, a second guide says another. This is the load-bearing disagreement on this page, and we left it open rather than averaging the two.
Whether a Respawn Capsule revive counts toward the level counter — unstated in every source we could find.
One guide claims a March 2026 patch improved the Undead's revive mechanics. Single source, no corroboration, and that same guide gets the class's arrival date wrong. Not adopted.
FAQ
Do the buffs stack? Each revive grants one buff from a five-item list, and the wiki says entries do not repeat. Whether the list caps at five or keeps rolling is disputed — see above.
Can I level the Undead alone? Only through Respawn Capsules, costing 1 / 3 / 7 / 15 / 31 Cultist Gems per buff. The wiki calls this not recommended.
What does Level 2's instant revive skip? The wait after being revived. At thirty revives, coming back stops costing you the downed timer.
Why move for 8 seconds after death if I cannot attack? So you can reposition. The wiki notes enemy aggro does not follow you during those eight seconds, which makes this a safe-move perk rather than a combat one.
Is +20 HP per revive a lot? Small on its own, and the only buff that visibly compounds with itself. Five of them is +100 max HP on top of the base — good, not game-changing. No source tells us whether the cap is five buffs or unlimited, so do not plan a build around either.
Does the sprint buff make me faster at everything? No. It applies to sprinting only, not walking or attacking.
Are Diamonds and Gems the same thing? Yes — one currency, two words. Explained on the Diamonds farming page.
