each war effort action within a spire system also has an effect on the 10 systems furthest away from the associated Titan - this is called "spread pushback".
[...] if any of the furthest 10 systems hit 100%, the titan will now start to affect the 11th system, then the 12th, and so on
Just to clarify, I guess the part I bolded should read "the spire will now start to affect" ?
