Fighting:

Terms:

hp: hit points 
dp: damage points, takes away from your power level (or hit points)
ki: the amount of ki you have
sp: speed, direct relation to your hp, if you lose 50% of your hp, your speed also goes down 50% making you much slower, and making it harder to dodge moves.

How to determine your hp 
its really easy to determine your hp, if your power level is at 5,000 then your hp would be 500, if it were 100,000 it'd be 10,000 hp. simple enough right ? 

Fighting itself 

if you take a Senzu bean during a fight you will recover all hp and half of your ki, if your hp is below 20 of what you started if your sayjian you'll get X.05% pl all others will get x.025%pl.

(Saiyans get more because through out the series it shows that Sayjians get much stronger after they heal and are seriously wounded) 

Everytime you gain 10,000 pl. every basic attack will gain 1 damage point (dp). Ex: punch = 1 dp. if your at 120,000. you gain 12 dp's. so punch would be 13 dp. Ex: Roundhouse kick - 5 dp. say your at 760,000. you gain 76 dp's. so a roundhouse kick would deliver 81 dp. 


Type Of Fighting 

Normal Fight - Winner gets 10 pl. and 5 speed. Loser gets 5 pl. and 2.5 speed. 

Fight To Death - Winner gets 20 pl. and 10 speed. Loser gets 10 pl. and 5 speed if human, 25 pl. and 12 speed if sayjian. 

If killed by a majin, the majin can abosrb you and gain 10% of your power and speed, you do not lose this power, he just gains it.

Group Battle - The battle requires 3 or more people. Winner gets 3x the amount for the win, loser gets 3x the amount for a loss. (max of 5 group battles a week)

Sparring - just like a normal fight, except there is no winner or loser and you do not coun't your hp in it. you get 8pl, and 4 speed per spar. and you can spar in higher gravity... level's change depending on the fight context and how well it was faught

Fighting in Higher Gravity - you can fight in higher gravity the higher the gravity the more pl you will get
