Astral Shambler

Astral Shambler

The astral shambler is a creature composed of writhing tendrils of ectoplasm. Nearly mindless, the creature has no custom, nor does it feature as a natural part of ecology anywhere. Instead it roams at random, attacking any creature that gets too close.

The creature walks along multiple limbs consisting of arms, legs, and tendrils.

Endless Consumption. An astral shambler attacks and attempts to absorb each creature it finds, except another astral shambler.

Ectoplasm Nature. An astral shambler doesn’t require air, food, drink, or sleep.
