In order to cast these skills. You need to cast an available skill thats similur to that skills element. Chi barrier is an Ice Spell. So you need to cast an ice skill thats available before using it. Which would be Ice Palm(key 3) or Ice Bolt(key F). After casting one of those, you have a another set of skills available on keys 1-4 and sometimes TAB. After casting a specific element those ones that become available.. are available for 10 seconds and it resets with each use of that element. So, use fire spell, 1-4 is active for 10 seconds. Use 1-4 or other fire spells will reset it again. If you use the opposite element itll change to that element and 1-4 will change to that elements skill set. Fire flower and chi barrier are allways active on the Tab key Upon use of that elements set of skills. -- Recorded Live on Justin.tv/Arecarws - http://j-tv.me/oNMIa9
