Well, devs envisioned Reaper to be end-game boss, and it only spawns when region level is 21 or above (about 13000 region score and more). Like a “super rival” to say so.
Though, only issue with this, is the current rival system, which will spawn rivals as low as 200 region score (in Guerilla difficulty) and by the time you get about 2000 region score, you can have all 8 rivals per region. And if one wants to spawn a Reaper, one has to avoid rivals, which gives this silly situation.
For a change in Reaper spawn, i’ll expand Carni’s idea;
One option could be where Reaper spawns after you’ve killed 40 levels worth of rivals. And Reaper spawns in that region where you killed the last rival that amounted the net of 40 or over it.
That would mean, that you’d need to kill:
- 10x level 4 rivals
- or 14x level 3 rivals
- or 20x level 2 rivals
- or 40x level 1 rivals
- or any combination of rival levels, as long as all rivals you killed, amount to total of 40 levels
(40 is just my example. It could be higher or lower, depending how difficult devs want the Reaper spawn to be.)
This would fix the issue of Reapers spawning just one after another and also gives sense of killing rivals = Reaper. Especially since killing higher level rivals means that Reaper will spawn much faster.
