Origin Avatar

During an Origin Trial the champion will assume the form of an Origin Avatar for the duration of the trial. Usually the champion will slip into the role of the being most similar to himself however if that being does not suit the trials objective another avatar is chosen. Countless researchers have tried to determine the exact pattern, but have failed, so many of them suspect that there is no concrete pattern.
The connection a champion forms with his avatar is a very mysterious thing but it is certain that the stronger the champions connection to the origin force becomes the connection to the avatar follows suit. Veteran's can often even inherit memory's and skills from their avatar whilst inexperienced champions often cannot utilize all of their avatar's potential. It is noteworthy that the vessel can be stretched to some extent to better meet the champions needs. For example a Strong knight can usually transfer his athletic skill and physical traits onto his avatar however if the discrepancy is too large and the vessel can't keep up the knights abilities will be contained.
Another detail better not overlooked is that many champions posses powerful artifacts blessings and such many of which cannot be shared with the avatar unless said avatar possesses the same or similar powers/artifacts.

"Weak... iv'e not felt like this in a long time, my avatar was but a shadow of my current physique and at first i did struggle with it. However with time i uncovered this was precisely my trial... to reach my goals not through strength but through craftiness a unique approach to say the least. Nonetheless i acquired the "Map of Hidden Steps" hrmpf" ~ Marcus Aurelius, Captain of the Royal Guard
