Spire Requirements Calculation

In this post I am going to outline how Spire of Eternity requirements – squad sizes and negotiation costs – evolve as you go higher in the Spire and do more encounters. As I have mentioned before, enemy squad sizes always have the same ratio to your own squad sizes. That ratio is different based on what that encounter position is in the Spire. And similar to that, your own squad size progression is also fixed. So squad size in later encounters is completely determined by your own squad size at the first encounter. And the same again goes for catering costs. Basically, once your weekly Spire is instantiated the whole setup can be represented by a single number. We can use different base numbers, but let’s pick your own squad size at encounter 1. Everything else will always be fixed with respect to that.

Encounter Progression

And this is how encounter progression looks like. Here it is:

Left side with Spire level, encounter number and number of waves is self-explanatory. Number of slots on the right is also straightforward – it’s the number of choices if you want to negotiate rather than fight.

‘Own’ column is your own Spire squad size for a particular encounter, expressed as a factor of the base Spire squad size (your first encounter Spire squad size).

‘Enemy’ column is your enemy‘s Spire squad size for a particular encounter, expressed as a factor of the base Spire squad size (your first encounter Spire squad size).

‘E x W’ column is a product of enemy squad size and a number of waves, as you’ll have to fight that many more enemy troops.

Example

So as an example, if your base Spire squad size (your own Spire squad size at the first encounter) is 1,000, you can quickly figure out what your final boss requirements are going to be. You will need to field 6,000 troops against 3 waves of ~5700 enemy troops, or 17,000+ enemies in total. This is going to be a tough fight 😉

Catering Costs

Now, Spire catering costs at any encounter are completely determined by your own squad size at that encounter. Here is how individual goods factors look like:

Basically, if your squad size for a particular encounter is 1,000, this would mean that individual gold requirements would be 77.5K, supplies 7.5K, ~1K of T1 etc. The game will round these goods numbers in a particular way around that.

Depending on where in chapters you are, you may not get all the variants. E.g. you won’t be seeing seeds before Halflings etc, but the factors do not change with chapter progression.

Spire Requirements Calculator

I’ve also made a nifty spreadsheet that calculates all Spire requirements based on your own base Spire squad size (at the first encounter). You can see it here:

• Spire Requirements Calculator (Google Sheets)

You will need to clone it, then populate your base Spire squad size (orange cell):

And that’s pretty much it 😉
