These are brilliant they're C attack seems to have a 180 degree AOE and MASSIVE knockback and they can shoot a projectile from the tail which slows things so much a gallimimus would look slow with it! The slowing projectile and the fact they're brilliant prime meat gatherers makes them excellent for helping to tame carnivores!.. only one problem... You have to let a wild reaper queen stab you and lay her egg in your chest then let the baby hatch out onto the floor and feed it using reaper pheromones to stop it eating you alive.
For raising if you let the baby kill you while your inventory is full of meat it can pick it up off your corpse if it doesn’t just drag the corpse and hold it where the reaper will run into it as it tries to attack you
I got a low lvl one using a strong bary (10 k hp and 300 damage) and i lvld up that reaper and usednthat reaper to get impregnated from a high lvl reaper, i now have a reaper with 50k hp and does over 1100 damage, and is able to take out several reaper kings on the surface. They are really good combat mounts and seem to be relativley fast. Almost nothingnwill aggro on u and they can bunny hop
