I can't really disagree with that assessment. in my head I saw rogue Leeches ruling towns in the wilds, Ripping power out of any who oppose them and being hunted down in civilized areas. Benevolent Leeches in civilized areas would function as healers of a sort, granting blind people sight temporarily or giving a restored youth to the elderly for a span.
On a different note, I fleshed out a different Form. Check it.
Iriscribe
Source: Emeralis sparked it, I ran with it.
Description: Has a large journal in which they describe the world around them, as well as multiple pencils, a pencil sharpener, and an eraser.
Clothing: Bright colors and a way to carry pencils. Beyond that, cut and form of clothing varies between Spheremorphs.
Abilities: An Iriscribe has a way with words, much like a Scribbler does with pictures. An Iriscriptor describes an object in his journal, fully and completely, and by adding a trigger word, which varies from Spheremorph to Spheremorph, to the end of the description can alter it. Everything about the object must be described in order for it to be altered
