TRAINING
Poof Spark
Blood Hit
This information is based on my own characters ,and information from broadcasts made by high level players.
as fas as I know CIP has never released info on advances.

My knight has 70 sword and my paladin has 67 distance, I only spend short periods of time training.
WEAPONS
Swords,axes,clubs and distance weapons advance on blood hits you inflict on a player or monster,but you must also be hit by a blood hit about every 15 times you inflict one.
In other words,if you hit a player 15 times and the player does not hit you back,you will no longer be working towards an advance.

  While training you should do as little damage to your partner as possible,this means setting both characters to "full defense" and using low damage weapons such as a longsword.Players will most likely have to remove armor to create a balance.

  Both players should be getting a good amount of blood hits,and also a good amount of sparks and poofs.

   Keep your characters eating to keep up regeneration of hit points and mana.this will allow you to train for hours.
 
It is very popular these days  to train with a ghoul ,having a sorc summon one and it stays stationary while you hit it , have something or someone else hitiing you , ghouls heal themselves .
SHIELDS
Shields advance on poofs,but you must inflict a blood hit on something about once every 15 times you receive a poof.
Characters(especially knights) who are trying to raise there shield skill should have two monsters attacking them while they are training.(bugs or wolves)

 
MAGIC
Magic level training of course is just the number of mana you use, One time I got a sorcerer to magic level 20 with just a fishing rod and casting light spell in two days.
  I have heard of people buying mana fluids and getting to magic level 30 in two days.
  Recent changes have made getting magic advances harder.

The reason why people buy large quantaties of food is so they can train in certain hidden areas away from keyboard.
