The <ahref="ah:context_help&target=ui:interface:phrase_book:content:content:sbtree&text=uiSkillTree">Skill Tree</a> allows you to see the state of your skills.
<BR>It displays the current level of the skill and its max level (eg: Craft: 1/20</a>).
<BR>The bar indicates the progression in the current skill level.
<BR>The color of the skill indicates either:
<BR>- transparent: skill not trained
<BR>- orange: skill currently trained
<BR>- green: skill completed
<BR><BR>When you complete a skill, a new part of the tree is opened, which you can see by clicking on "+".
<BR>The whole skill tree is not displayed. Only completed skills, currently trained skills,
and the untrained skills that relies directly on a trained skill are displayed.
<br><h4>Actions</h4>
The Actions part shows the actions you can learn or the actions you have learnt at each skill level.
<BR>You have to <ahref="ah:context_help&target=ui:interface:phrase_book:content:content:sbtree:tree_list:0&itext=Select">select a skill</a> to see the actions related to this skill.
<BR>The actions you have not learned are grayed out.
<BR>The actions you cannot learn because you do not meet the requirements (e.g. you don't have the required skill level) displayed are in red.
<BR><br>You can drag and drop an Action to your action bar, but you cannot drag an Action Upgrade because they are either characteristic upgrades, or action upgrades
