while most ecruws went down dramatically in price, a few did not due to rare costumes which i have listed below. I spent 2 hours researching this so yes I know what I am talking bout. Please keep this in mind when offering on these kinds of ecruws.

Mermaid Ecruw (unstatted, well named)-12million
Fire Ecruw (unstatted, well named)-11 million
Baby Ecruw (unstatted, well named)- 20 to 25 million
Wizard Ecruw (unstatted, well named)17-20 million

These prices are based on either costume+maker or potion depending upon which is searchable.

If the pet is statted, caculate 7k per level in the major stats (strenght, health, speed, defense). Magic and Charisma DO count and should be regarded as worth 10k per Magic and Charisma level. The price on these two is subjective and is estimated at 10k since you cannot regularly train in these area..and are dependant on luck in their respective dailys

Most pet guides will tell you that if a costumed pet comes in a potion you must go by the potion price not the LE creator+costume. Below is my attempt to track some of the potions.
