When breeding, make sure you breed the pair in a good spot. You CANNOT pick up the egg. Bump up so people can see.

WARNING:If a tamed bloodstalker gets to low enough health, it can and will begin to eat you (if you are "riding" it)

Whilst raising them use bloodpacks and MAKE SURE you keep the packs in their inventories. If you put bloodpacks in troughs and leave render, they will not eat from it.

If a survivor has ingested beer, a tamed Bloodstalker’s name will temporarily change while under the effects of said alcohol. Try it out for yourself, some of the names include “Blerdsterker”, “Mr. Wiggles”, and my personal favorite “Grabby McSlurpy”.

My results so far after a bit of testing:

Can double jump, can climb, can walk on water, highlights creatures, can shoot bio tether to grapple and drag creatures to you (including flyers) can shoot a single tether to swing around or shoot 2 simultaneous tethers to propell you forward or to set up position to ambush. Keep holding the tether button to pull you towards the tether point and accelerate speed. (ps4) L2 for double tether (disconnects automatically after pulling you to the point) R2 for single tether (doesnt disconnect automatically). Can move extremely fast when tethering correctly.
