Rappelz/Levels/Stamina and condition

You can see the amount of SP your character has by placing the mouse over the coloured bar under the green HP bar and the blue MP bar. A window appears stating something like this:
 * Excellent Condition
 * Recovery Rate 30%
 * Stamina 1531/5000

The amount of stamina a character has influences the character's condition. Every time your character kills a monster you see (in the chat area) a message like this:
 * You have gained 814 EXP and 92 JP
 * (Stamina Bonus Was: 407 EXP +46 JP)

The second line means some SP (in this case 24 SP) are converted to EXP and JP.

Condition
The condition of your character can be normal, good or excellent. The better your character's condition the higher the stamina bonus when killing monsters.
