levels 45-50
Max exp 500
Min exp 300

If the opponent sends you to within 10% of your health, i.e critical you get the full 500+bonus

If its 20% of your health i.e critical verging on serious you get 480+smaller bonus

If you rape a hole in someone and take a very minimal amount of damage i.e you are still in healthy, except for 10 damage or something then you get the lowest exp of 300

Somewhere in between working of % of damage for the 360 exp, 420 exp etc

Simples.
