These are some of the observations that I noticed when using roots. Please note that different fighters from different fighting styles would perform differently. The roots are used only as a booster or enhancer and you may find that your observation might be different from mine.
The following changes were seen when roots were used after a prolonged period of time (used 5 days on and 5 days off method)
Tough and Shiny scales - observed under magnifying glass
More aggresive - Flares even when there's a shadow of movement
Very alert to surroundings
Powerful spring attack - coils like snake, jump and bites at female during training
Improved appetite when taking food
Fewer scale drops during test fights
Longer endurance during female chasing activity (using long plastic flower bucket)
During test fights attacks faster and is able to conserve energy by fighting smartly
Fighter positions well with opponent and minimise exposure to vital attack points.
Overall improvement of fight duration after using root and proper training.
