So far, mainly encountered them around the portal (easy spawn). Tame passively with aquatic mushrooms. New mushrooms in aberration can be obtained through plant foraging, yielding fiber, sometimes berries and mushrooms. Use as a shoulder pet to help deter but not stop the nameless. It will hold a “charge”. Certain pets and charge sticks (able to be kept in inventory) are able to be recharged at (currently green colored) computer terminals. I’ve seen three along the river banks in the central area of the map. Beware of all the spinosaurs and krakinos.
Many new environmental and creature variables are included in abberation to punish the unprepared players. The nameless to name a few.
