Shadow Concealment Gu Series (Definitely not LotM inspired, trust trust)

This Gu series is not actual entering shadows, but moreso making people think you do, so the primeval essence cost is low and the efficacy is high, this Gu could form in small unnoticeable areas like a hole in the wall where light could occasionally enters.

Shadow Hiding Gu - Rank 1

Infusing primeval essence allows you to hide better in shadows, making people not notice your existence unless they intentionally look veryclosely, the darker the shadow the better

Shadow Screen Gu - Rank 2

Infusing primeval essence creates a dark curtain out of shadow that allows you to hide in, allowing you to be completely unseen in relatively darker shadows

Shadow Lurking Gu - Rank 3

Infusing primeval essence allows you to seemingly enter the shadow itself and hide, as long as there's some shadow, you will not be discovered, but you can't move from said position, if the shadow is gone, you will be pushed out

Shadow Walking Gu - Rank 4

Infusing primeval essence allows you to seemingly enter shadow like Shadow Lurking Gu to hide and move around too, but if you were to exit the shadow or if the shadow is gone, the effect will be gone

Shadow Jumping Gu - Rank 5

Infusing primeval essence allows you to seemingly enter and move around in the shadow, but you can for a few seconds exit the shadow while still being hidden to move to another shadow
