If you force tame a seeker, you can ride it. So you can fly around Aberration.

It acts as a glider when on your back I tamed one on single player and used it for getting around

Force taming using admin command means you can become this creature, dont jump off near a wall otherwise you will fall through the world

Put glow horn in box light them all and throw seeker in ther to tame seeker

They act as gliders when on your shoulder you jump off a cliff and press forward and shift to dive

You can tame it with a room with a ton of charge pets and other sources of light,but I force tamed one cause I dun have time for that,it looks like you ARE the seeker when you ride it and it is the only rideable flyer that you can increase its speed because of the flyer ban.

If ever your reaper gets stuck in the bury position simply whip them to get them to move to a new spot and unbury them. (Worked for me, had it stuck on the edge of a cliff plat)

Will not attack charge lanterns and will fight nameless when wild
