If you put foundations under the reaper it can not burry. This way you can keep farming the same reaper for the best stats because every baby reaper, even if its from the same queen, will have different stats.

gestation timer stuck at 0:00 still persist for those who still plays UME official servers. just eat organic polymer to reset and wait out the timer.

Trap the reaper queen on foundations - that way it can't burrow after it impregnates you, and can do it again. This way, you can have multiple kings.

I tried this and I know it will work, to tame an R-Reaper, I went into rockwells innards with a shadowmane, and weakened the reaper that way, it force dismounted me and started the cutscene, the shadowmane interrupted it cause it wasn’t on passive

With the release of ASA Aberration, WildCard released an update making Reaper King baby levels based on a combination of player, mother and XP levels. I have worked out a rough formula for level distribution.

Reaper Queen Level + ( Player Level ÷ ( 155 ÷ Bonus Levels ) )

For example: A level 130 Queen, 91 player and 75 bonus Levels comes out to. (Current max attainable player level is 155, this may change with future expansions)

155 ÷ 75 = 2.0666~

91 ÷ 2.0666 = 44.046

130 + 44 ( rounded ) = Reaper King Level 174

Thanks to contributions of other tips, here is what I found useful:

1. You can gain bonus level XP while mounted. You do not need to run on foot to kill stuff while impregnated

2. Once the baby hatches and eats your body or dino body (if you use a pheromone), you can claim the baby then cryo it to prevent it from continuing to run. (This may be a bug)

don’t use the blood extraction syringe while pregnant it will remove the pregnancyy!!

Spend hours finding high level queen.

Get pregnant.

Give birth in base with walls as high as a behemoth gate.

Lose baby magically.

Thanks ark.

6/18/2020. You can still transfer pregnant to genesis. You can still weigh it down with meat. Dont believe the other posts

I lost my megalosaurus named Sleep Demon while trying to tame one of these guys

If you trap the reaper queen on foundations it can’t burry away after it impregnates you so the rest of your tribe can all get pregnant off one queen. Plus you can kill it once your done for some free levels on the baby <3

Head over to aquatica Abyss and in the air bubble cave thing, Abyssal reaper queens spawn, no oxy stat which means a level 150 is comparable to a normal reaper level 180, except these also dont drown... and are faster in water, same taming tequnique (however you spell that lol)

Somthing i just learned if u need to go offline while pregnant the pregnancy timer doesn't go count down when you're not on

Drop everything, encumber yourself with food. Let the baby kill you, and you won't need to worry about watching it for all least a day. The 8 hour baby time means NOTHING

As of October 2020, you can transfer between servers without losing the baby. If you go to Crystal isles, you'll still have the baby but the timer will stop and will go back to normal once you travel back.

So I will make this as simple as I possibly can so if you want one of these bad boys for one of your maps and you play single player then go to gen 2 now go to the Rockwell infected part of the map and then go to rockwells in are to find the cave area it’s in the middle part of the infected area so you go in to the boss terminal and look for a reaper queen they are bigger than the kings and have different tails so once you have found one bring it into the acid pool under the boss terminal the acid goes away and comes back every 2 minutes I think so then scan the queen with hlna and watch until it gets to 2k health then you have to lead it out of the acid pool and then it will do a sniff animation and then pick you up you will be at one health after it impregnates you so be careful leaving rockwells innards and then when the time comes make a box so the baby reaper can’t escape after you give birth if you want it to be a baby reaper immediately then cryopod it if you have one and want too welp there you go sorry it was so long ;)

Maewing DOES feed baby reapers,

When raising you can use a maewing/Maeguana to feed by putting the reaper in the saddle basket. Even if you don’t have astraeos in Asa you may still be able to obtain a Maegauna through trading they make it much easier to raise and will feed offline as long as the maegauna has food

Make sure you have some heals on you when the reaper queen impregnates you!!

If your finding low levels and don’t want to kill them. Kite them off a cliff and leave the render distance of said cliff and poof. They despawn and instantly respawn a new reaper. Once you find a good level (120) above for me. Try trapping it on foundations. That way when it impregnates you it won’t bury underground leaving you left to kill it and get max levels on the baby reaper. REC. use magnifying glass to see how low it’s health is. Health for impregnation should be below 2500. Then your ready!

Since Dododex hasn't added the raising times I will.

12 hour pregnancy

7 hour 30 minute baby stage

Total maturation time 3 days 3 hours

Total time with pregnancy 3 days 15 hours

Baby reapers eat 6 stacks of cooked meal per hour.

45 stacks should be enough to account for spoilage until it's out of baby stage.

To feed baby reapers easier make an airlocked pen and get a though full of cooked meat in your inventory 5 minutes before it hatches. Use a pheromone gland 3 minutes before birth and then claim it and stay in it's inventory. Force feed it cooked meat as it bites you since biting you makes it lose food. Then once it kills you it should collect all 60 stacks into it's inventory. Use a gland to make sure and if not feed it until gland wears off and stand on your body so the reaper eats the body.

Good luck!
