Is the PEAK Tomb Open Today?

The Tomb is a secret area beneath the Mesa. Its entrance — a mound of rock with a hole in the middle, on the plateau in the first half of the Mesa — is open on 42 of the 103 Mesa days in the current pool. The Mesa itself is only in the rotation on some days. The status below updates automatically at each daily reset.

Why the Tomb is worth checking

The Tomb is the only place in PEAK where you can find the Ancient Idol, and the Idol is the only way to earn the 24 Karat badge (reward: the Bing Bong Beanie). Carry it to the top of the island and throw it into the lava of the Kiln or the lava cauldron in the Citadel, and every living player gets the badge. Picking the Idol up also counts as obtaining a mystical item for Esoterica.

The Idol is heavy, at 40 weight the heaviest item in the game, but it makes whoever holds it invincible. Most status effects are ignored while you carry it, though stamina still drains as normal and the weight still fills your bar.

How often it is open

The Tomb depends on two rolls, and both are fixed for the day:

The Mesa has to be in the lineup. It shares region three with the Alpine and appears on 103 of the 208 islands in the current pool.
In the current pool the entrance is open on 42 of those 103 days. Alpine days have no Tomb.

The pool repeats on a fixed 208-day cycle, so an island that had an open Tomb will have it again when that island comes back. How the daily map works explains the cycle.

Using the status box and map above

The table counts each location once. Open a row to jump to that location in 3D. Open 3D map
Red means skip it. On a closed day there is nothing to find under the mound, so cross the Mesa normally.
Note the next open date. The line under the status shows the next day the Tomb opens, so you can book the run with friends in advance.
Check the finale too. Both finales have lava, so the badge works either way, but the biome rotation tells you which climb follows the Mesa.

Practical tips

Eat before the challenge chamber. It is a dark pit crossed on wall holds, and running out of stamina halfway is the usual way to fall.
Take a torch from the entrance hall. The rest of the Tomb is dark.
Do not linger. The fog does not rise inside the Tomb, but it keeps rising outside while you are underground.
Pass the Idol around. Handing it between players spreads the weight, so nobody is stuck with a crippled stamina bar for the whole climb.
Do not count on the Tomb statues. They are decorative, unlike the ancient statues beside campfires.

Common mistakes

Searching on closed days. A filled-in mound is not a puzzle. It means the Tomb is shut for this island.
Dropping the Idol before the top. The badge needs the Idol thrown into lava at the end of the climb, not left at the Mesa.
Forgetting the Mesa itself. The sun, cacti and antlions are still there; see the Mesa guide.
