I have had so much trouble getting into this champion stuff.
You're the one who asked for "Arcade Mode"
That's not the only inspiration behind it, but is one of them.
A question on the new Heroic AI type.
How does it value Champions for wave sizes?
It just adds the champion on top of the wave that's there.
Ps the whole Epsilon Eridani mission takes for ever.
Half an hour is within the target range, though I find it generally takes me more like 15 minutes, or less depending on how I do it.
If your ally fleet gets wiped out, and it's a late enough scenario that the enemy is getting a lot of scaling bonuses, then the central starbases spawns could be pretty frequent, yea, but by then you would have a pretty big champion and have more flexibility to make stuff happen. One key thing is to keep your ally's anti-starbase ships (the lowest-tier ones) alive by shielding them from enemy starbase fire and killing the enemy mid-tier ones. Depending on how big you are and what modules you've specialized in, you can do enough damage to the enemy starbase that cover from nearby allies, your shield ability, and your shields will allow successful attack runs of your own.
If it's one of the early scenarios it can basically be steamrolled in 10-15 minutes by your allies if you use the shield ability judiciously and kill off those enemy mid-tiers before they gobble up the ally anti-starbase ships.
Is the Champion even meant to be balanced with the Fallen Spire game?
Yea, it should work with pretty much any other setting, or at least not break it. In FS's case I think I'll just take an earlier suggestion and make the champion have only a very minor impact on FS exo size. I mean, a champion is a threat, but compared to even a 2-city fleet...
