Thanatos Tower Quest & MVP

The full Thanatos Tower chain works on dewataRO. It ends with summoning Thanatos Phantom, the MVP that drops the Memory of Thanatos Card (0.8% here, versus 0.01% official).

This is a long chain with several steps that will silently stall you if you don't know the trick. Read the Traps section before you start.

Two things you can do here

They are separate. You do not need the quest contract to summon the MVP, and finishing the quest does not summon anything.

Getting in

Use the Warper. Talk to the Warper in any major town (prontera 159,192) → Dungeons → Thanatos Tower → pick any floor 1-12. Free, instant, no requirements.

The official route (Tower Keeper at hu_fild01 140,163, 5,000z entry, then a floor-by-floor climb) still works, but one step in it — the F2 to F3 gate — requires 5 players standing in the same small square at once. On a server our size that will basically never happen. The Warper skips it entirely.

⚠️ The one thing the Warper cannot skip is the F6 → F7 doorway, because that is where your Black Key becomes a Black Charm Stone. See Part 1 step 6.

Part 1 — The five key puzzles

Do these in order. Each one gives you a key.

1. Red Key — Rune Device, tha_t03 67,70

Pick "Investigate it."

⚠️ You must be holding a level 4 weapon in your right hand — or be a Taekwon class, who bypasses this. A level 3 weapon fails. This is the single most common place people get stuck, and the NPC gives no hint about it.

2. Yellow Key — Rune Device, tha_t04 195,195

A number-guessing minigame. Enter a 3-digit number with no repeated digits and no zeros. It tells you how many digits are right after each guess. You get 5 tries; fail all 5 and it just tells you the answer and picks a new one, so you cannot lose anything.

3. Blue Key — Brilliant Statue, tha_t05 62,179

Bring the Red and Yellow Keys (they are not consumed). Choose to stick a key into the crack, then type the key name exactly:

Red Key
Yellow Key

4. Green Key — Brilliant Statue, tha_t06 226,230

Bring Red + Yellow + Blue Keys. Choose "Investigate" → "Investigate the Wheels", then set all five wheels to the same state. Any all-matching combination works. Option 6 shows the current configuration, option 7 resets everything.

5. Black Key — Splendid Sword, tha_t06 204,181

Bring all four keys. Choose "Observe it." → "Towards the hilt of the sword" → "Insert the sword into the hole".

⚠️ The other options cost you 20% of your HP and give nothing.

You also receive Varmunt's Note here — that is your quest turn-in item.

6. Black Charm Stone — the F6 → F7 doorway, tha_t06 119,120

Walk onto this tile carrying the Black Key. It is consumed and you get the Black Charm Stone.

Requirements to pass:

• 2nd class, transcended, or 3rd class — or Super Novice / Taekwon / Star Gladiator / Soul Linker / Ninja / Gunslinger / Summoner at base level 95+
• 1st classes are blocked outright

This doorway is the only source of the Black Charm Stone on the server.

Part 2 — Turn your keys into Charm Stones (Floor 8)

On tha_t08 there are Shining Crystals in four colours. Talk to the one matching your key while holding it — the key is consumed and you get that colour's Charm Stone.

⚠️ Only one crystal per colour is active at a time, on a 40-minute rotation. If you arrive and see nothing, the quest is not broken — you are between rotations. Wait, or go to the coordinates that are currently live:

You need all four: Red, Yellow, Blue, Green. (Black already came from the doorway.)

Part 3 — Feed the five statues (Floor 12)

On tha_t12, insert your charm stones in this exact order. Each statue announces to the whole floor when it is fed.

⚠️ This progress is server-wide, not personal. Every player on dewataRO shares one set of statues. Five different people can each insert one stone, and if someone else is mid-chain your statue will refuse you ("the light is too strong"). Announce in chat before you start so nobody collides — a stranded stone is stuck until the 2-hour reset.

The fifth statue opens a glowing gate at tha_t12 130,52. Step on it and you are taken to the boss map — but the gate is selective. It only lets through players with Thanatos Tower quest progress, the player who fed the final statue, or members of that player's party. Everyone else gets a refusal message and stays on Floor 12, so farmers can no longer be dragged into someone else's boss room by walking over the tile.

Handy: the Warper's "Thanatos Tower Floor 12" destination drops you directly on that gate tile — but warping there only gets you in if you are part of the run (quest progress, the seal opener, or the opener's party).

Part 4 — The boss room

Bring these first

Four Memory Fragments, one of each. They drop from the four Thanatos guardian mobs scattered around the tower, at effectively 100% on our drop rates:

Break the four seals

Four Memory Seals sit in the corners of the boss map. At each one, type the fragment name exactly — capital letters matter:

Each seal releases a guardian (level 129, around 30,000 HP — not a boss). Kill it, then move to the next seal.

When the fourth guardian dies, everyone on the map is automatically pulled to the summon spot. A 16-second cutscene plays, then Thanatos Phantom appears.

The fight

⚠️ You have about 36 seconds to loot after it dies. The map then force-warps everyone back to Floor 12. Pick up your drops immediately.

⚠️ Cooldown is 2 hours and it is server-wide. After Thanatos dies, nobody on the server can summon it again until the reset.

Abandoned runs clean themselves up. If a group breaks the seals but wipes or leaves before Thanatos falls, the tower resets itself within 2 hours: leftover guardians are removed and all four seals reopen. Stray guardians from an old run can no longer break the summon sequence — if you kill more guardians than expected, the ritual still proceeds normally.

Claiming the quest reward

Separate from the MVP. Once you have Varmunt's Note (from the Splendid Sword), return to Burled at tha_t02 231,161, choose "Start a conversation", and hand it in.

• Old Purple Box ×1
• A large EXP payout, capped at one full level

Afterwards, talking to Burled has roughly a 1-in-3 chance of a free heal.

There is also a repeatable turn-in at Liei, tha_t01 140,78: 1,000 zeny each for Golden Ornament, Red Feather, Blue Feather, and Cursed Seal, any quantity. Zeny only — no EXP.

Traps that stall people

1. Level 4 weapon on the Red Key step. Level 3 will not work. Taekwon classes skip the check.
2. Typed answers are case-sensitive. Fragment of Misery works, fragment of misery does not.
3. Floor 8 crystals rotate every 40 minutes. Nothing is broken — check the rotation table.
4. Statue and boss progress is shared by the whole server. Coordinate in chat.
5. The F6 → F7 doorway is mandatory even if you Warper everywhere, because it is the only place the Black Charm Stone exists.
6. Floor 11 is open PvP. It is the fastest Fragment of Despair farm, but anyone can attack you there. Floor 7 is the safe alternative.
7. A server restart wipes statue and seal progress, since it is held in temporary memory.
8. Killed the fourth guardian and nothing happened? That was an old bug (stray guardians from an abandoned run confused the ritual counter) — it is fixed. If you ever see it again, wait for the 2-hour self-reset and report it on Discord.
9. Refused at the Floor 12 gate? Working as intended. The gate at tha_t12 130,52 only accepts players with quest progress, the seal opener, or the opener's party — if you are just farming F12 with no quest progress, it will not pull you in.
