Kingdom Under Fire: Heroes Hints

On firths mission went you are told to catch the P run your hogs into battle with the paladins on the back left hand side and you will get 2000sp.

Since KUFH gauges experience differently (the game determines the cost of a
skill increase on the total skill levels instead of a particualr skill), you
will want to keep all the skills of one leader or officer within one level of
each other to avoid paying an exorbiant cost of increasing a skill. For example,
if you have a leader with a melee of 9 and a range of 1, your cost of increasing
the range skill from one to two will be the same as increasing your range skill
from nine to ten. By increasing your skills equally, you will be able to
economise on the skill points you spend.
