既然是个CLASS FEATURES，你没有就是用不来
我的理解就是，用不来的就是上面这个部分……
以下的部分跟rune master的class feature是没直接联系的……还是可以正常用。
THE RUNIC KEYWORD
When you are going to use a runic power, you first choose
one of the runes noted in the power and then use the
power, applying the chosen rune's effects. The moment
you choose the rune, you enter its rune state. You remain
in that rune state until you enter another rune state or
until the end of the encounter.
RUNE MAGIC
（前略）
When you use a runic power, you choose one of the
runic alphabets with which to empower your prayers,
often tracing a rune in the air as you use a power. Your
choice of runic alphabet alters the workings of the power.
Using runes of protection might enhance the power's
bonus to defense, whereas using runes of destruction
boosts its damage.

又及：RC的P119，里面说明了Runic关键字。Choose first；Rune state，这两个效果可没说一定要符文大师特性……
