Excavations

**In-game description:**
*Enter the Archeology Association to control the progress of your Excavations. There you will be able to fund more excavations to find Faction Coins, the rare Rubies and ancient Artifacts from the civilizations of the old.*
**Excavation** was first implemented in the *"Ancient Races"* expansion for introducing Neutral Factions. With any luck, Excavations allow you to find Faction Coins, Rubies, and—depending on certain thresholds or conditions—Artifacts. Some Artifacts are required to unlock the Neutral and Prestige Factions.

Some Lore Artifacts will reward direct bonuses, but most do not reward anything. Rather, this latter category of relics count towards the total number of Artifacts discovered. Moreover, specific (total) quantities of Artifacts discovered is a requirement for some upgrades (e.g., the Research upgrades D290, E330, or the *Fossilized Rodent* Artifact).

## Requirements

The below only has to be bought once throughout the entire game and does not show up as bought upgrade.

## Costs & Find Chances

The first excavation costs 1 Oc (1E27) coins, and each subsequent excavation costs 20% more than the last.

* **Excavation Reset:** The excavation counter and cost are reset by reincarnation. Alternatively, you can buy an excavation reset for 1 Ruby up until 2999 excavations, 2 up to 5999, 3 up to 8999, 4 up to 11999, 5 up to 14999. It will reset the excavation counter to zero, all previously gained Excavation rewards and Rubies will persist and you can not find them again.
* Free Reset: Free resets will be available if you get enough excavations. It will let you reset your excavations without spending rubies. You will receive a 90% production penalty until you abdicate. The minimum excavations required will go up by 500 after every free reset. When you reincarnate the minimum excavations added by making free resets will be eliminated, but it will increase by 50.

**Formula**: 2000 + 50 \* R + 500 \* x where x is amount of resets this R.

* **Faction Coins**: Each excavation has a 35% chance (40% with That Excavated Quickly) to produce faction coins.*Formula:

{\displaystyle floor(2 \* ln(1 + (5000000 \* 1.15^x))^3)}

  where x is the number of excavations you have (not including the one just purchased).*
* **Rubies**: 1 Ruby is found at excavation 50, 150, 300, 500, 750, 1050, 1400, 1800, 2250, 2750, 3300, 3900, 4550, 5250, 6000, 6800, 7650, 8550, 9500, 10500, 11550, 12650, 13800, 15000, 16250, 17550, 18900, etc. Formula for the number of excavations required for each ruby:

## Artifacts

There are 102 Excavation Artifacts:

* 24 Quest Artifacts that unlocks the Neutral Alignment, Research and Research Slots.
* 78 Lore Artifacts

All artifacts with a random chance check that chance on every individual excavation if their non-random requirements are met. How the excavations are purchased is irrelevant, and artifacts will be found on the same excavation number regardless of whether multi-buy is used.

**ATTENTION!** : Vanilla Faction-specific Lore Artifacts cannot be found if affiliated with a Prestige Faction. (e.g.The Fairy artifacts cannot be found if you are also playing as Dwarf.)

## Tips

* **Flame of Bondelnar:** To reach excavations above 3250 to obtain the flame, see Flame Chance research build.

**Lore Artifacts:**
* **Stone of Balance, Translucent Goo, Bottled Voice, and Huge Titan Statue**: Disable druid Challenge 4. For Stone of Balance, don't purchase the Druid spell upgrade Halls of Balance. Ensure you have enough mana regen to cast the spell the artifact is based on constantly. For Stone of Balance, enough casts of Grand Balance will come naturally when attempting Dragon Challenge 2, assuming that you don't affiliate with Dragon until after generating 1e10 mana.
* **Divine Sword, Demon Horn**: Only the Faction Trade Treaty is required for an affiliation. You can check consecutive affiliations using Royal Scribe.
* **Undead Jaw Bone:** The 3rd and 4th Drow Challenges do not increase your offline time outside of the run you use them on, and the artifact cannot be obtained with drow, so the challenges do not help obtain the jaw bone.
* **Know Your Enemy, Part I:** This is related to the Harlequin Secret Trophy. See Joker merc build.
* **Dawn/Dusk Stone:** The time used to check eligibility is your local system time.
* **Translucent Goo:** To get it faster you can use brainwave then export and import your save and repeat that.

## Notes

* **Excavation chances**: Artifact finds are based on your game's RNG seed, so you can test excavate in a private window and get the same results when excavating in your real game. For the same reason, using "Buy Max" or not, find chances are identical. Read more about excavation chances here.
* **Excavation Cap:** Calculated for v1.6.50.4. Without any cost reductions value breaks on 3553rd excavation, so you can only buy up to 3552 excavations max. With only one of currently available reductions (Ancient egg, during Easter event / E290 research upgrade) cost value breaks on 4016th excavation (4015 excavs available). With both of currently available cost reductions value breaks on 4634th excavation (4633 excavs available). See calculations.
As of v2. Post ascension maxes out at ~16,811 without using E290.
* **Artifact Sets****:** upon getting all faction-related artifacts (3 for each faction), you get that faction's artifact set. Artifact sets work like bloodline, and will give you a boost.
