Then, as you level up, you sort of bricks you use to modify the action. For exemple, you start with the action "fight", the you buy "hard damage 1", then "Accurate attack1"...
With thoose, you obtain "Stamina credit 1", wich means that to use the action "hard damage 1", you'll use some stamina. But you can buy "life credit" and instead of using stamina, you'll use some life points. Then you can buy "Strike after evade", to make strong attacks without using stamina or life at all. You can then create your own attack :
You create a new action, then add the options "Strong Attack 1", "Accurate attack 1", "Bleeding 1", then you add the credits "Stamina credit 1" and "Strike after Evade" to equilibrate your attack.
Then, you can fight softly, and when you evade, you'll land a strong blow.
The more you go up, the more you gain new "stanzas" (it's the name of the skill bricks you use to build your actions), and the more you have room to use different techniques, so you can really customize your game experience and make the caracter of your dreams : I wanted to be able to do Everything, and believe me, I do
But my progression is very slow as compared to a specialised player. Believe me, for discovering and understanding Ryzom, 14 days is short, so dive in the game and good luck!
