+        ・判定コマンド(nWAFx+x または nWAIxRx)
+          WAFコマンドはRageダイスとダイスプールを個別に指定する。
+          WAIコマンドはRageダイスをダイスプールの内数として指定する。
+
+            例：難易度2、9ダイスプールでRageダイス3個の場合、それぞれ以下のようなコマンドとなる。
+            2WAF6+3
+            2WAI9R3
+
+          難易度指定：成功数のカウント、判定成功と失敗、（Rageダイスがある場合）Brutal outcome、Critical処理、Total Failure、Critical Winのチェックを行う
+          例) (難易度)WAF(通常ダイス)+(Rageダイス)
+              (難易度)WAF(通常ダイス)
+              (難易度)WAI(通常ダイス)R(Rageダイス)
+              (難易度)WAI(通常ダイス)
+
+          難易度省略：成功数のカウント、判定失敗、（Rageダイスがある場合）Brutal outcome、Critical処理、Total Failureのチェックを行う
+                      判定成功チェックを行わない
+                      Critical Winのヒントを出力
+          例) WAF(通常ダイス)+(Rageダイス)
+              WAF(通常ダイス)

+              WAI(通常ダイス)
+
+          難易度0指定：Critical処理と成功数のカウントを行い、全てのチェックを行わない
