So, how exactly does the philter of trait disruption work?
Does it randomize the traits of your sylesti?
Does it only randomize the visible traits or the carried ones too?
Is there a chance for a carried trait to become a visible trait when using this? Does it add any traits to an empty slot or only randomize if there is already something in that slot? Does it only work on themed pets?
If so, is there a version for normal pets too? Does it work on exclusive pets or on starters?
Does it work on offspring of themead pets or does it have to be a 100% themed pet(one that has that purple writing on their profile saying what theme they are)

It randomizes the traits of your themed sylesti.

It randomizes both visible and carried traits.

There's no chance for the carried traits to become visible, it just shuffles the current trait points. (If your pet is 2-Vis, 2-carry, it would shuffle the traits and still be 2-Vis, 2-Carry, but the traits would be different.)

It only works on themed pets, the pet must be tagged and unbred.

There is no version for normal pets or starter pets. It only works on pets with the "purple text" tag that shows that it is a themed pet, of which can be exclusive or tamed.

It does not work on offspring.

I've answered what I could. I haven't got personal experience in relation to pets that have carried traits so someone who's Philtered a pet with carries might be able to provide more insight (alternatively, you could see if you can find any carries in this thread and see what the end result was: Show off your Disrupted Pets)

Does it randomize the traits of your sylesti?
Yes, it reshuffles them.
Does it only randomize the visible traits or the carried ones too?
I believe it reshuffles all trait points. I can't say I've personally ever used the Philter on a pet with carries though.
Is there a chance for a carried trait to become a visible trait when using this?
I assume not. I assume carries will remain carries. Visibles will remain visibles but I could be wrong. Maybe someone that has used a Philter on a pet with carries can clarify?
Does it add any traits to an empty slot or only randomize if there is already something in that slot?
Hmmm... how to explain. There's not limit to the reshuffle. As a result, say you had a pet with visibles in M1, M2 and M3, if you used the Philter, the result would be 3-visibles in M1, M2, M3, G1, G2 or G3. (If you're really unlucky, the reshuffle can even result in the traits you already had).
Does it only work on themed pets?
Correct. The Philter of Trait Disruption (Themed) only works on themed pets.
If so, is there a version for normal pets too?
No.
Does it work on exclusive pets or on starters?
It does not work on starters. It only works on exclusive pets if there's also themed. Example.
Does it work on offspring of themead pets or does it have to be a 100% themed pet
Only themed pets. It will not work on purebred offspring.
