Killing a Rival drops the region score and level. To spawn a Reaper, region level should be at least 21 (that’s about 13000 region score). The higher the region level after 21 is (max is 25), the more likely is that the Reaper spawns in that area.
In a nutshell: if you want Reaper to spawn, stop killing Rivals.
Ok but I see you only have 4 rivals, maybe if a zone is already full then there is no room for the reaper to spawn?
yes your counting right. There are 22 rivals in the farmlands. (cause the rivals from the other zones came looking ;))
and yes I keep my rivals alive and feed them sometimes. If you give them cookies then they dont bite trust me 
totally agree, except that there is a problem the more we go up the region and the less machines there are in the region, I have to attract machines from another region to the region concerned to do climb the points of the region, the robots are becoming too rare for skirmish mode. Normally the process should be the reverse, Fnix being alert on the region (s) it should send more machines.
I often spend 30 to 45 minutes to find small troop of hunter or runner (from level 20, tanks and harvesters are very rare (except rivals but the goal is not to destroy them)), and it quickly gets boring :se lasser::persévérer:
I look the absence of machines as “calm before storm” since once Reaper does spawn, you’ll have the hardest fight on your hands.
Also, to help to increase the region score, i take out relay beacon guards while leaving relay beacon intact. So, the next time i come to the area, i have the same machines to take out to increase the region score.
Ok got the reaper spawned. He counts as a rival too, so it seems that he cannot spawn as long as your “full” on rivals, meaning make sure that you only have 7 active rivals in a zone.
I’m just gonna chip in on this as following the live stream, it wasn’t well explained - as well as some consistency issues BUT - in light of recent spawn I can offer this }
Despite Pontus’ and Reece’s ( WIRED GAMING ) regions both being below minimum requirements for it to spawn, it must be at level 21 for all us simple folks.
Also worth clarifying for 100% clarity - IF you have 8 rivals setup in a region IT WILL NOT SPAWN A REAPER. You need an available slot for it to generate, which will either be from the next level cap of the region, OR 2500XP ( still to be confirmed ) whatever comes first.
Respawning the Reaper for subsequent farming is pretty annoying so far. It feels like this update changed something with region spawns; I remember always running into a harvester (and company) on the road right outside of Anl 118 Farela but have not found it since this update. In the Marshlands at least, I’ve kind of resorted to wandering around randomly or killing Harvester Rival Hunter summons to increase my region score. It’s pretty tedious and doesn’t feel like targeted farming; there’s a lot of just wandering around the map looking for anything to kill.
The other issue that I’m running into is that after two Reaper kills, my Marshlands has accumulated 8 Rivals. Killing a level 4 FNIX Tank Rival seems to drop my region score around 4k points. I’m worried that in grinding the Region Level back up to 21 (for me at Skirmish difficulty this seems be about 11300 region score) I’ll just end up spawning another 8th rival instead. It would be nice if the Reaper did not count as part of the 8 Rivals and could spawn if 8 Rivals were already in a region.
I’m a little afraid to experiment, but does anyone know if the score decrease on killing a Rival changes based on machine type, Rival level, game difficulty (currently playing on Skirmish), or even current Region score/level? Is there a cap to the Region score?
AfaIk the region cap is 25 and yes, the decrease of region points depends at least on machine type and Rival level and from my experience I’d say also on the class of the rival. So killing a level 4 APO tank Rival nearly ruins your region score… ;-/ at least in the lower sections up to 10-12
Thanks, I guess I’m clearing out my Hunter rivals as soon as they spawn then 
Tip: keep at least 1 hunter rival alive. Since when you get your region level to 22 or so, ice the hunter and you have good chances of spawning Reaper, without the hunter kill lowering the region level outside the Reaper spawn criteria (lvl21 and above).
Hmm… to purely level up a region that might not be the best idea, imho.
Even though Hunter rivals give nearly no rival-loot (at least in my gameworld), they’re useful to have at the end when the regoin points cross the 21 border and you have 8 rivals in it. And if you kill it early, a Harvester or Tank rival might spawn instead…
Sad fact about that, I had already all my regions levelled up to have 8 high type & class rivals and killed nearly all hunters during that process, to get the best chances on higher rival-loot…
I’m in the same situation as you are. I also have several regions filled with only rival tanks, all are lvl4 rivals.
Regions where i don’t have all 8 rivals per region as tanks, are: Archipelago (worst region to level up), Forest, North Coast (both regions are low level, <5) and Himfjäll (best region to level up).
So, i’m currently in Himfjäll, leveling it up and i hope that if the Reaper spawns, it doesn’t spawn next to any other of my 6, lvl4 rival apo tanks, that i have in Himfjäll.
I sure hope the current system gets a complete rework when it comes to spawning the reaper, since how it’s implemented currently feels counterintuitive to say the least - kill only the small critters to raise region score, which in turn makes that region spawn rivals. Kill a rival to “make room” for the reaper, and the region score drops again.
This is perhaps the most clumsy mechanic I’ve stumbled upon in any game, and it simply doesn’t make sense.
I have a question: Does the Reaper is bound to the same respawn timer as all regular Rivals?
I just leveled Farmlands to 25, destroyed lowest of the low Rival… and another regular Rival showed up 
That’s what I’m thinking as well.
Exactly the same situation last night, which spawned a Military Tank instead of the expected Reaper.
I was under the impression that with 7 active rivals, providing your region level is above 21 - it would spawn every time on the 8th rival. It would seem there is more to it
OK, I think that the Reaper spawns outside of the standard 2h timer. I just destroyed the fresh rival… along with 4 Tanks, 2 Harvesters, and gazillion of Hunters and Runners (NW part of farmlands 
) and finally it spawned.
Good man like it.
I’m streaming all my Reaper kills, so should be easy enough to figure out actual game time based on Reaper death to Reaper spawn based against stream clock counter.
A Reaper will only spawn at level 21 and above, The higher the Level from there the more chance you have of spawning Him (Keep in mind there is a 2 Hour gap between each Rival Spawn, I believe) The Maximum amount of Rivals Per Region is 8, and a Reaper Counts as a Rival, so you must make sure you only have 7 Normal Rivals in Your Region, in Order to Spawn a Reaper. Don’t Kill a Rival Unless you Absolutely Need to, Unless its the Reaper
