The marriage bonus applies if your spouse is in the same team as you, and kills a monster while you're on the screen..
If you're a water tao, the bonus is 100%
If you're not a water tao, the bonus is 20%
The marriage bonus only applies if the monster your spouse kills is less than twenty levels higher than yourself.
Your spouse's level doesn't matter at all.
Noob bonus:
The noob bonus gives a benefit of 100% team experience to all classes.
To get the noob bonus, you must have a character in your team who is more than twenty levels lower than the monster being killed.
The noob, you, and the person making the kill must all be relatively close to each other for the benefit to take effect.
The monster in question must be atleast twenty levels higher than the benefactor of the noob exp for this bonus to apply.
Water Bonus:
Somewhat unsurprisingly, the water bonus only applies to water taos!
You get this bonus at lvl 70, when you get your water wizard promotion.
It is a 100% increase which applies only to team experience. In other words, if you kill a monster yourself, it won't do anything, but if your team leader kills it, you will get 2x what you would.
This bonus, like the marriage bonus, only applies to monsters less than twenty levels higher than you.
/vip - To control vip features.
Exp pot bonus:
Simple. Use an exp pot, get 2x exp for an hour. This applies to all exp except DB/exp ball/vp exp.
