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
Chapter_One_'The_Fear_Within'Spelunking Pages – Chapter One ‘The Fear Within’  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_StampMultitool 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_DimwitSkilled Dimwit Prayer A strong prayer that is useful for all skills and should be maxed. Unlocked by completing Wave 25 of Goblin Gorefest.
spelunking-alchemy-bubble-spanpunkieSpapunkie – Green Alchemy Bubble Unlock and upgrade this alchemy bubble which requires you reach the second map of World 7 for Doodlefish drops.
idleon-equinox-broadbass-card50px-Chaotic_Troll_CardEquinox 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.

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
SpelunkingShop42Amber Run SpelunkingShop14SpelunkingShop4Increase 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).

SpelunkingTunnel3Object6SpelunkingTunnel4Object6SpelunkingTunnel5Object10Rotate between RustBelt_03, Blushpit and Chucklemire with Overstim initially as you want a tunnel you can reach a deep depth for amber multipliers to apply. After you defeat the Glitter End lore boss this will be the best amber tunnel instead by a significant margin and eventually Scoutpost at e30+ POW.

  • SpelunkingShop36Destroy all objects on each depth to buff Jobs All Done shop upgrade. SpelunkingShop22
  • Reach as far as possible to buff Deep Pockets shop upgrade.SpelunkingShop23
  • Escape with the rope when it is too risky to continue for the Rope Subsidy shop upgrade multiplier.
SpelunkingShop15Depth Run / Manic Mode SpelunkingShop3SpelunkingShop10Reach 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.

  • Destroy as few objects as possible to save stamina and focus solely on pushing depth.
  • Don’t worry about escaping with the rope as your focus is maximum depth.
Spelunking_Shop_42Discovery/Grand Discovery Run SpelunkingShop2SpelunkingShop11Unlock new discoveries or grand discoveries to increase POW (Discovering the POW shop upgrade) and Amber gain (Amber from ‘Em All shop upgrade).

Spelunking_Shop_45Spelunking_Shop_43Normal Discoveries are the yellow circles on the lore boss page while Grand Discoveries are the pink gem shapes. Most Grand Discoveries will be on the earlier tunnels where you can destroy lots of the final object before they resist your attacks.

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.

  • For normal discoveries destroy each object once to unlock it.
  • For Grand Discoveries push for depth while saving stamina. Once the depths are predominately the final object type use a Grand Discovery elixir and destroy as many final objects as possible .
  • These are all the final objects for grand discoveries (for example the Stonespire in Pebble Cove):SpelunkingTunnel1Object6SpelunkingTunnel2Object7SpelunkingTunnel3Object8SpelunkingTunnel4Object9SpelunkingTunnel5Object10SpelunkingTunnel6Object11SpelunkingTunnel7Object12SpelunkingTunnel8Object13SpelunkingTunnel9Object14
  • A pop up will appear on screen when a new grand discovery is unlocked. idleon-grand-discovery-popup-small
SpelunkingShop30Item 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. SpelunkingShop28SpelunkingShop29

  • Send a single character focused on maximising objects destroyed for stamina spent.
  • Try to take the escape rope to prevent the toll tunnel exit cost.
SpelunkingShop38Boss Run You’ve reached the recommended boss POW level and this is your only focus.
  • Push to the boss depth saving stamina for the boss.

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
Amber Runidleon-spelunking-amber-runidleon-spelunking-amber-run-alt2
  • Maximises amber multiplier
  • Can swap in one purple shadow elixir in first setup for faster clearing.
  • Use the second elixir setup for Glitter End and Scoutpost as the high stamina allows the orange amber potion to give a significant boost when used with only 2-3 characters of stamina left. Add a red POW elixir if these tunnels are newly unlocked to help push depth during your first amber run at lower POW levels.
Depth Run/Manic Modeidleon-spelunking-depth-runidleon-spelunking-depth-run-alt
  • Maximises stamina and destruction
  • Replace or combine green POW elixir with red heart POW elixir when unlocked if you have plenty of stamina but need more POW
  • Also used for Manic Mode, initially you can use 3 purple elixirs as you will not go deep enough to need the Red/Green POW elixirs.
Discovery/Grand Discovery Runidleon-spelunking-discovery-runidleon-spelunking-discovery-run-alt
  • For normal discoveries use the depth run setup instead
  • Adjust stamina potions based on your character levels to ensure you reach the last discovery.
  • For later tunnels add in the red heart POW elixir to offset the grand discovery elixir POW loss and maximise last discoveries you can destroy in this grand discovery setup.
Item Runidleon-spelunking-item-run
  • Maximises object destruction and stamina. Can also add a single blue potion instead of purple for the chance to regain stamina repeatedly.
Boss Runidleon-spelunking-depth-runidleon-spelunking-boss-run-alt
  • Same core setup as depth run
  • Swap purple shadow elixir with red heart POW elixir when unlocked

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.
