Spark - Modification (Common)
Modification is a part of the Spark Aspect of the Clay Fysa. All luto start with this fysa.
This is an active fysa. The user can mold their own bodies to create new limbs or change their build. They can also assimilate new substrates and objects, or grow plants out of their own body.
The only thing a luto has difficulty changing is its mask. The mask is molded by its "parent" and most changes to the mask are things like paint, cracks, or chips. Luto who lose their masks or sustain too much damage lose their minds, becoming mindless constructs-- these moving, mindless forms die after a short while.
Potential - Adaptation (Rare)
Adaptation is a part of the Potential Aspect of the Clay Fysa.
This is an active fysa. Users can absorb the body of a deceased animal or plant, taking its abilities as well (ex: a poisonous plant to gain poisonous abilities). The more a user does this, the less control they have over their sentience/autonomy and they threaten to destroy their own identity. Doing this to a too-powerful or sentient creature will surely destroy a user's mind and shortly after kill them.
Terraform is a part of the Spark Aspect of the Clay Fysa.
This is an active fysa. The user can temporarily become one with earth, water, or plants, touching and merging with them in order to manipulate them. This roots the user in place while they are doing this, and it uses up energy. It is safer to use this when one has Esse.
Inanimate is a part of the Structure Aspect of the Clay Fysa.
This is a passive fysa. Users can incorporate artificial structures as more than just an accessory on a normal luto-- they can control these parts like any other body part. This includes being able to control clothing, artificial limbs, tools, and toys as if they were normal limbs.
Invoker is a part of the Potential Aspect of the Clay Fysa.
This is an active fysa. One can use the power of a name to bolster or debilitate another. The truer a name is to someone's identity, the stronger this power is. This is part of the reason that certain species used to hide theirs (such as Ptheran, who knew about the Luto's abilities), though aliases and titles can still be invoked as well.
Buffs and Debuffs are small however, mostly causing energy or fatigue, and don't last for more than an hour.
