Spoiler warning! This article contains spoilers about Era content. |
Era is a phase of the game which opens up at Military Tier 8. Era begins when the player reaches wave 100B in endless mode on any difficulty of a given region.
Upon reaching Era, enemies gain an Era shield and various Era powers, depending on their element.
Every time you hit wave 100b, the era counter increases by 1. For example, if you are in era 5 and hit wave 100b, your era increases to 6.
There are several ways to combat the era enemies' shield and various powers, which most are found in Workshop-->Stairs
Here is a general overview of Era workshop. INCLUDES SPOILERS!(credit to @TECHTERROR731 on the discord)
Contents
Tab 1: Era Information
In the first tab of the stairs, you will find various bars, 2 for each element to fill. In order to fill these bars, you must kill era enemies of that element and get hit by them (You must take at least 0.1 damage to count as a hit) during tower testing. Once a bar is filled for an element, you can reveal it to find out one of the element's era powers. When both bars are revealed for one element, that element may now be disabled and will appear in tab 2 and unlock tab 2 if you haven't already done so. You may need to reach era in different regions if you want to reveal all the elements.
Tab 2: Era Research
In the second tab of the stairs, you will find many bars and buttons. At the top, you will see your era dividers. These divide the era shield of era enemies so it is easier to destroy and survive them. You can increase your dividers by pressing the two buttons beside each icon. Under your era dividers you will find a variety of bars and buttons. These let you decrease the cost to disable the powers of each element. The two buttons over the bar will let you speed up the process, at the cost of some hits taken and enemies destroyed. Decreasing the cost to disable the enemy's era powers down to 950xp will make that element appear in tab 3 and unlock tab 3 if you haven't already done so.
Tab 3: Era Experiments
In the final tab of the stairs, there is a bar and many tabs. The bar will let you decrease the cost to temporarily increase your dividers while in a round of the tower testing. You can also speed up the process by using gems once you get the Chained Mannequin or you can speed up it with the power plant once you get the Ominous Coil artifact. Doing an upgrade will upgrade one of the two dividers randomly, except eventually you will want to fully upgrade this so the randomness doesn't really matter.
Formulas, where lvl
is the number of already purchased upgrades:
- Upgrade cost is
1.2lvl * 1e15
blue resources. - The cooldown timer after an upgrade lasts
900 - 3.75 * lvl
seconds. - The cost to skip the cooldown is
1.08lvl * 1000
gems. - The initial (displayed) XP cost for a divisor is
ceiling(0.95lvl * 1e5)
. - Upgrade
lvl
maxes at 240 (120 upgrades for each, capping at 213 XP).
Under the bar there are many tabs. These let you gain elemental essence which can unlock modules to the right of the bar. Once you get to Military Tier 9, elemental essence will also give you a damage boost for each essence you have.
Era Divisors
The Era divisors reduce (divide) the effect of the Era multipliers, which (besides the Era Powers) are one of the biggest obstacles in Era. With each subsequent Era, both enemy damage and enemy HP are multiplied by 10^(20 * era^(1 - level/300 * 0.78) / (level+1))
, where level
refers to the Workshop Era Dividers upgrades bought. After a few hundred Eras, the multipliers will exceed 1.8e308 (the largest double value) and become infinite, which is represented by a skull and cannot be reduced to a survivable amount by normal means.
To combat this, you can invest XP in the Era Divisors, which divide the multipliers by 8 for each level. Once the divisor amount exceeds 1.8e308, it becomes infinite as well, and (due to game coding) this infinity takes precedence, completely superseding the Era multipliers for the rest of the run and clamping them to their minimum value of 1x. This is sometimes known as "disabling the Era Shield."
However, the initial cost of the divisors is very high - 100000 XP. To be practical, you must use the button in tab 3 in the workshop to reduce the XP cost. Each upgrade multiplies the cost by 0.95, and which one is chosen (HP or damage) is random, but it doesn't matter because you'll want to max them both. Once you've upgraded both 120 times, the cost function will be ceiling((100000 + 10000 * num_upgrades) * 0.95120)
= 213 XP initially, growing by ~21.2 each upgrade. This reduces the XP cost to max a divisor to (at most)
(342 * 100000 + 342 * 341 * 10000 / 2) * 0.95120 + 342
= 1310537 XP, and less if the tab 2 upgrades have been bought.
Era Powers
Every enemy has certain powers based on the element it has. These powers can be disabled by using the new Era tab during Tower Testing, at the cost of Tower Testing XP.
The formula for the XP cost of disables is base_cost * (100 + 0.9 * base_cost)disables
, where base_cost
is the initial cost (starts at 1000, but can be reduced in Tab 2), and disables
is the number of already-disabled powers.
Note that the costs of already-disabled powers don't matter, so it can help to save your lowest-cost disable for last.
The enemy powers are as follows:
