How To Increase Spelunking Efficiency
Is is common to have low initial Spelunking efficiency which makes it difficult to level up Spelunking. These are the best initial sources to AFK at the Fearful Tunnel on the Equinox Broadbass map (Refraction Bend) as these scrolls add significant Spelunking efficiency and speed:
| Source | Notes |
|---|---|
Spelunking Pages – Chapter One ‘The Fear Within’Â |
Farmed on the Equinox Broadbass map active or AFK Spelunking pages are critical to long term progress in this skill. Read all the scrolls you can farm daily by splitting them into 5 different stacks initially and then 8 after your total account Spelunking level is 500 as rift level 16 increases the max number of daily reads. |
Multitool Stamp – All Skill Efficiency |
A powerful stamp which is an important account boost to all skills. Obtained from World 5 Poigu on the Lampar Lake map. |
Skilled Dimwit Prayer |
A strong prayer that is useful for all skills and should be maxed. Unlocked by completing Wave 25 of Goblin Gorefest. |
Spapunkie – Green Alchemy Bubble |
Unlock and upgrade this alchemy bubble which requires you reach the second map of World 7 for Doodlefish drops. |
![]() Equinox Broadbass & Choatic Troll Cards |
These two cards boost Spelunking efficiency and can be doubled with World 4 Laboratory card doublers. The Equinox Broadbass card becomes passive after your total account Spelunking level is 300 from rift level 16. |
Pit O’ Pages – Royal Guardian Talent |
The Royal Guardian has several Spelunking boosting talents including Pit O’ Pages which adds Spelunking Efficiency and Speed for farming Spelunking pages. |
Spelunking Strategies – Amber, Depth, Grand Discovery & Bosses
Spelunking is focused on a repeating loop of activities that increase your POW level and amber gain to reach the required POW to beat lore boss battles. These lore bosses are the primary boosts to your account alongside a small number of amber shop upgrades for Kattlekruk bubbles, statue drop, masterclass drops, drop rate and time skip items. These are the different spelunking activities to spend stamina on which require different elixir setups and strategies to maximise gains.
| Run Type | Purpose | Strategy |
|---|---|---|
Amber Run |
![]() Increase your highest amber run on a tunnel for immediate amber and increases your daily amber generation (Unexplainable Daily Amber Gains shop upgrade) and increases POW (Hauling the POW).
|
|
Depth Run / Manic Mode |
![]() Reach new maximum depth on a tunnel which increases POW (Depthing the POW shop upgrade) and Amber gain (Amber from the Depths shop upgrade).
As you reach new POW levels remember to backtrack to past tunnels and set new depth records. In late game Spelunking Manic Mode is unlocked in the shop which increases stamina costs by 30x. Manic Mode depths have POW, Grand Discovery and Spelunking Efficiency boosts. |
|
Discovery/Grand Discovery Run |
![]() Unlock new discoveries or grand discoveries to increase POW (Discovering the POW shop upgrade) and Amber gain (Amber from ‘Em All shop upgrade).
Grand Discoveries are rare so increase your chances with the Spelunking shop upgrades, Zenith Statues, Sushi Station (Tier 22), Chapter Five lore scrolls and Minehead Purrhead. |
|
Item Run |
Farm Exalted Stamp Fragments, Prisma Bubbles, Snail Mail, Blinding lanterns and Sigil Syrup from tunnel runs.
These item drops and unlocked in the amber shop with upgrades increasing the drop chance. |
|
Boss Run |
You’ve reached the recommended boss POW level and this is your only focus. |
|
Combine with these general spelunking tips:
- Read Daily Scrolls: Place characters at spelunking tunnels on the world map to farm readable scrolls to buff various spelunking elements and read all scrolls obtained each day by splitting them into stacks (5 reads per day initially and then 8 after 500 combined spelunking level and Rift level 16). The first tunnel you encounter on the Equinox Broadbass map is one of the strongest scrolls to improve your Spelunking efficiency for more scrolls per hour so even reading these daily is useful. As you progress read Chapter Two ‘Decay (Shellslug map) and Chapter Six ‘Kelp (Kelpfish map) as both of these have POW and Amber multipliers. All the Spelunking pages are noted in the wiki along with the minimum thresholds required to be read in a single stack for a chance to get a particular lore journal buff.
- Spelunking Upgrades: Most amber shop upgrades are useful to your spelunking progress goals so level them to the same cost while checking the impact to your POW number and amber number (shown in the shop). Column one has the strongest POW upgrades while column three has the best amber upgrades but there are many utility upgrades in the shop you can max along the way.
Best Elixirs
The best spelunking elixirs vary based on the type of run, max number of elixirs and the elixirs currently unlocked. All elixir related upgrades are a priority and after the hidden elixirs shop upgrade you can find extra elixirs during a run. In late game progress players can double down on these potions with Elixir Memorisation to start with extra potions of the below.
| Run Type / Best Elixirs | Notes |

Depth Run/Manic Mode![]() ![]() |

Discovery/Grand Discovery Run![]() ![]() |

Recommended POW For Bosses
These are my recommended boss POW requirements and individual character stamina to comfortably defeat a lore boss but you can defeat it earlier with some luck. The majority of your free to play POW will come from Spelunking upgrades in the first and fifth columns of the shop. Other sources include lore chapter reading bonuses or different game mechanics with lore boosts (Summoning, Farming, Gaming Palette, Meals, Slab) that slowly add up.
The red heart POW elixir will be unlocked around the time you progress to Bizzario and the numbers below include using it with the green POW elixir from that tunnel onwards.
