Here we see Bruvelighe displaying the effect plane Obeisant Ichor in action!

By drawing forth the varicolored blood of a dying stellar god, Warpjaws can employ a versatile range of abilities--the viscous fluid comes in a variety of colors, each performing different functions based on hue. Strangely the ichor itself is partially sapient, allowing it to be controlled and directed telepathically from the summoning Warpjaw.

The purple goo shown here is capable of creating surprisingly hard barbs and thorns from its surface. When coating an individual it can then be used as a form of defensive armor or--as shown above--a type of weapon, and by swinging their limbs around they can become a kind of living flail. Additionally these thorns can be flung from limbs as a rudimentary projectile. Puddles of this hue may also be left on the ground...which then become crude spike traps for unaware enemies.

Below is a cheery mnemonic for some of the other colors:

A caustic attack, blooms from black
Be something new, covered in blue
Purple is prickly, tricky, sticky
Obscene is green, but seldom seen
A friendly fellow, comes from yellow
But if it's red, you're good as dead

This awesome looking comm was drawn by  neltruin! They did such a great job with that acrobatic pose and all those thorns!
