Endless Mode
(This Page hasn't been Updated for the 1.0 Changes.)
Endless Mode is a game mode that can be toggled on and off in the Menu when you are selecting a Danger Level to play. See the picture to the right.
When playing in Endless Mode, the game doesn't end after beating the final Wave 20, but instead keeps going until you die.
As the waves progress, the difficulty of the game dramatically increases, ensuring your demise.
If you managed to beat at least wave 20, the run will count as a win when you die.
Wave 20 Changes
If you're playing on Endless Mode, Wave 20 lasts 60 Seconds instead of 90 Seconds, and killing the spawned Boss/Bosses doesn't instantly end the wave.

Post Wave 20 Changes
Once you finish Wave 20, endless mode begins. From here on out the game changes significantly:
Piggy Bank Stops functioning entirely.- Harvesting
Stops increasing by 5% at the end of each wave. Instead it decreases by 20% at the end of each wave. The increase from 
Crown or playing 
Farmer also stops after wave 20. So you'll still lose 20% even if you have Crown. You can still increase your harvesting stat by upgrade, items, or other means. - Elites and Bosses are nolonger Guaranteed to drop Loot Crates and when they drop loot crates, it is a regular crate instead of a Legendary Loot Crate.
- The Endless Factor begins to increase, affecting many aspects of the game.
Materials
The Drop chance of Materials from enemies is dependent on the current wave. See the Materials Page for more information.
In Endless Mode, the Base Chance, 100%, is reduced by 1.5% times the current Wave. The minimum chance is 50%.
An important takeaway is that characters such as 
Cryptid, 
Fisherman, Farmer, 
Streamer, and 
Explorer that have reduced materials drops from enemies actually end up having 25% drop rate once you get to wave 34+ in Endless Mode.
On The other hand, 
Jack just has a permanent 100% drop rate for 3x materials throughout all waves due to a bug in the coding.
| Wave | 21 | 22 | 23 | 24 | 25 | 26 | 27 | 28 | 29 | 30 | 31 | 32 | 33 | 34 | 35 | 36 | 37 | 38 | 39 | 40 |
|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|
| Drop Chance | 68.5% | 67% | 65.5% | 64% | 62.5% | 61% | 59.5% | 58% | 56.5% | 55% | 53.5% | 52% | 50.5% | 49% | 47.5% | 46% | 44.5% | 43% | 41.5% | 40% |

| Drop Chance Jack | 100% | 100% | 100% | 100% | 100% | 100% | 100% | 100% | 100% | 100% | 100% | 100% | 100% | 100% | 100% | 100% | 100% | 100% | 100% | 100% |
Wave Structure
The Endless Waves are grouped together in 10 waves at a time.
Each 10th level, (So Wave 30, 40, 50 etc.) you'll face Both Bosses. No matter which Danger Level you're playing on.
You'll also face 0, 1, or 3 Elite Waves depending on your danger level. Horde Waves does not spawn after Wave 20.
In addition, +1 Elite is added to Elite Waves and Boss Waves for each 10 Waves that has passed.
So Wave 21-30 Adds +1 Elite. Wave 31-40 adds +2 and so on. These Elites can be dublicates, and multiple of the same elite often spawn.
This 10 Wave structure continues on until you die, with the Endless Factor ever increasing.
The Endless Factor
In order to ramp up the difficulty of the game, the Endless Factor is introduced.
The Factor is calculated as follows:
Endless_wave = max(0, current_wave - 20) Endless_mult = 2.0 + max(0, (current_wave - 35) * 0.2) Endless_factor = max(0, ((endless_wave * (endless_wave + 1)) / 2) / 100) * endless_mult
The things to notice are:
- The Max function takes the highest of two numbers. It is used here to make 0 the lowest possible value.
- The Endless Factor starts at 0 and only starts growing from wave 21 and onwards.
- From Wave 36 and onwards, the Endless Multiplier is an addtional scaling that kicks in and causes the Endless Factor to scale faster.
The end result, (And all you need to remember), is that you get a single number that the difficulty of many things are multiplied with.
Here is the Endless factor at different waves:
| Wave | 20 | 21 | 22 | 23 | 24 | 25 | 26 | 27 | 28 | 29 | 30 | 31 | 32 | 33 | 34 | 35 | 36 | 37 | 38 | 39 | 40 |
|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|
| Endless Factor | 0.00 | 0.02 | 0.06 | 0.12 | 0.20 | 0.30 | 0.42 | 0.56 | 0.72 | 0.90 | 1.10 | 1.32 | 1.56 | 1.82 | 2.10 | 2.40 | 2.99 | 3.67 | 4.45 | 5.32 | 6.30 |
At the bottom of the page you can find the Table over all the effects of the Endless Factor.
Now we will go over the different things that are affected by the Endless Factor.
Enemy Stats
Most importantly, the Endless Factor increases the Stats of all enemies.
Damage
The Damage of Enemies increases with 100% of the Endless Factor.
Endless Damage = round(Damage * (1 + Endless Factor))
Where:
- The Round function rounds the number to nearest whole Damage value.
This means that enemies have their damage increased by the following percentages from wave 20-40:
| Wave | 20 | 21 | 22 | 23 | 24 | 25 | 26 | 27 | 28 | 29 | 30 | 31 | 32 | 33 | 34 | 35 | 36 | 37 | 38 | 39 | 40 |
|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|
| Damage Increase | 0% | 2% | 6% | 12% | 20% | 30% | 42% | 56% | 72% | 90% | 110% | 132% | 156% | 182% | 210% | 240% | 299% | 367% | 445% | 532% | 630% |
Max HP
The Max HP of Enemies increases sharply with 200% of the Endless Factor.
Endless Max HP = round(Max HP * (1 + Endless Factor * 2))
Where:
- The Round function rounds the number to nearest whole HP value.
| Wave | 20 | 21 | 22 | 23 | 24 | 25 | 26 | 27 | 28 | 29 | 30 | 31 | 32 | 33 | 34 | 35 | 36 | 37 | 38 | 39 | 40 |
|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|
| HP Increase | 0% | 4% | 12% | 24% | 40% | 60% | 84% | 112% | 144% | 180% | 220% | 264% | 312% | 364% | 420% | 480% | 598% | 734% | 890% | 1064% | 1260% |
Speed
Speed slowly increases with 10% of the endless factor. The speed increase from the endless factor has a limit of 275%.
Endless Speed = Round(Speed * (1 + (min(1.75, Endless Factor / 10.0))))
Where:
- The Round function rounds the number to nearest whole speed value.
- The min function means that the increase can never be more than 175%, meaning that the endless factor can't increase speed more than a 2.75 factor.
- Speed is the Speed of the enemy with other changes to speed already included.
This Speed Factor is multiplicative with the base stat and the secondary stat. So speed modifiers from effects such as 
Snail and 
Old still matter.
| Wave | 1-20 | 25 | 30 | 35 | 40 | 45 | 48+ |
|---|---|---|---|---|---|---|---|
| Speed | 100% | 103% | 111% | 124% | 163% | 230% | 275% |
The Shop
Item Price
Endless Item Price = max(1.0, ((Item Price + Wave + (Item Price * Wave * (0.1 + Endless Factor / 5 ))) * items_price_factor))
Notes:
- Item Price is the base price of the Item or Weapon. This price can be modified by the
Arms Dealer's ability of -95% Weapon Price. - The Endless Factor used is the value of the Wave you've just completed. So when you finish Wave 50, that is the value used for the Endless Factor of the Shop. The top of the Shop says number of the next wave.
| Wave | 20 | 21 | 22 | 23 | 24 | 25 | 26 | 27 | 28 | 29 | 30 | 31 | 32 | 33 | 34 | 35 | 36 | 37 | 38 | 39 | 40 |
|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|
| Price Increase in %
of Item Base Price. |
0% | 8.4% | 26.4% | 55.2% | 96.0% | 150% | 218.4% | 302.4% | 403.2% | 522.0% | 660.0% | 818.4% | 998.4% | 1201%% | 1428%% | 1680% | 2154% | 2717% | 3379% | 4150% | 5040% |
The Price Increase in % of Item Base Price means that if you buy an item, the Percentage is added on top of the item's price at that wave.
For example if you buy a 
Gnome on Wave 40, 5040% of its base price is added on top of its price from the endless Factor.
Without the endless Factor, the Gnome would have cost 540 Materials. But because of the endless factor, 5040% of 100 = 5040 is added on top of the price.
So instead the Gnome costs:
540+5040=5580 Materials.
Generally, the Shop Prices increase dratically in the Endless Mode. So get your shopping done before it is too late.
Rerolling
The price for the Reroll Increase in Endless Mode is determined by:
max(1, last_reroll_value + max(1, (0.5 * wave * (1 + Endless Factor))))
Notes:
- The max function is used to ensure that the price of rerolling is at least 1, and at least increases by 1 with each wave.
- See Shop Rerolling to understand how Rerolling works.
Here is a table of the prices of rerolling in Endless Mode:
| Wave | 20 | 21 | 22 | 23 | 24 | 25 | 26 | 27 | 28 | 29 | 30 | 31 | 32 | 33 | 34 | 35 | 36 | 37 | 38 | 39 | 40 |
|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|
| First Reroll Price | 30 | 31 | 33 | 35 | 38 | 41 | 44 | 48 | 52 | 56 | 61 | 66 | 72 | 79 | 86 | 94 | 107 | 123 | 141 | 162 | 186 |
| Price Increase per Reroll | 10 | 10 | 11 | 12 | 14 | 16 | 18 | 21 | 24 | 27 | 31 | 35 | 40 | 46 | 52 | 59 | 71 | 86 | 103 | 123 | 146 |
Recycling
Recycling is not affected by the Endless Factor, so the amount of Materials you get for recycling an item is actually 25%, or 60% with 
Recycling Machine of the Item's value without the Endless Factor was applied to it.
Miscellaneous
Here are the rest of mechanics that are affected by the Endless Factor.
Consumables
The Endless Factor affects the chances of an enemy dropping Consumables
Consumable Drop Chance = Unit drop Chance * (1 + luck/100) * (1.0 + (Endless Factor * 3.0))
- The Drop chance has a maximum of 100%.
- You can see the drop chance of enemies Here.
Loot Hoarder, Elites, and Bosses have a guaranteed consumable drop.
Trees has a 100% base chance of dropping a consumable. But it doesn't have the "guaranteed". This means the negative luck and the endless factor can cause trees to have a chance to not drop consumables.
This means that no matter the Endless factor, those three type units will continue to drop consumables and Loot Crates unaffected by the Endless Factor. Trees on the other hand, along with every other enemy will begin to drop less and less consumables.
Iframes
Iframes, or Invulnerability Frames, are a duration of time after taking damage, where you cannot take damage again. This is what prevents you being hit more than once when you walk into an enemy.
The Iframe Duration has a minimum of 0.2s and a maximum of 0.4s. See the Iframes for more details.
Once the Endless Factor becomes larger than 1, it begins to influence the duration of your Iframes as seen below:
Minimum Iframes = Base Min Iframes / (max(1.0, Endless Factor)) Maximum Iframes = Base Max Iframes / (max(1.0, Endless Factor))
So an Endless Factor of 2 halves your Iframes, 3 makes it a third and so on. This means that on later waves, walking into enemies can instantly deal damage to you multiple times. Enemy Projectiles tend to disappear after hitting you, so they will still only hit you once.
See the Table for percentages on Iframe Durations.
Giant Belt
Giant Belt is coded to lose effectiveness when you get to the higher levels of Endless Mode. Starting at wave 39, the belt begins to deal less than 10% and 1% of current health. You can see the percentage of effectiveness for the Belt below:
| Wave | 1-38 | 39 | 40 | 45 | 50 | 60 | 75 | 100 |
|---|---|---|---|---|---|---|---|---|
| Effectiveness | 100% | 94% | 79% | 38% | 22% | 9% | 3% | 1% |
Endless Factor Tables
