Tips & Strategies

If anyone is breeding them, or yours is low health blood packs also heal and feed them fairly well, you can probably drain food with stimberries and put blood packs in their inventory to speed up the process. The rates for food consumption, health recovery and your breeding would affect how effective they are.

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.
The bloodstalker is a spider like creature. Cheats a substance out of its mouth and allowing you to use it as a grappling hook type thing to pull yourself onto stuff. Substance is also used to swing around just like Spider-Man. I'm definitely getting one!!! To swing around from object to object you must be riding the creature
