What I've learned from battling these to find an R-Reaper:
1. As you've probably read, they project a spotlight passively, if you find yourself within this cone of light, prepare for a fight.
2. THEY HAVE A SHIELD. Save your ammo/element, their shield only comes down for approximately 1-3 shots of a tek rifle, or one shot of a shotgun. If working with another player time your shots & shoot together.
3. It's either summons or spikes! They will shoot a round of spikes at you OR they will shoot a slow moving purple ball down towards the ground, causing dinos to spawn. Unless the spawns are fliers just ignore them, stay in the air, and continue the fight.
IMPORTANT NOTE: The shield will stay up until it finishes the attack or finishes spawning in dinos, stay on the move until then!
These things are like watch guards. They have a light that shines from them that when you go in it they summon R variant creatures that are super hard to kill. It also has “babies” that appear after acquiring mutagen or spawning naturally, these swarms are a MUCH worse version of the insect swarm. Good luck to anyone encountering this!
Figured out a really good way to avoid these things in the cave is to use a shadowmane since you can go invisible to un agro them. Works really well as Rockwell’s innards are pretty difficult with these things everywhere
Whenever you encounter one of these things, or plan on encountering, or just found it, you should most likely bring some flak armor and a pump action shotgun, also make sure to bring a few extra pairs of armor, because when this thing attacks it is completely invulnerable. Hope this helped!
once they spot you with their light they shoot some kind of projectile and that spawns different creatures that will attack you i’ve come across snow owls, bats shadowmanes, quetzals, sabertooths, argy etc. best way is to not get spotted if u get spotted the light will glow red
Although you cannot tame regularly, you can force tame it if you do you are able to ride on it just like the boat destroyer aka the leed which also cannot be tamed regularly but when it’s force tamed it can be ridden on!
