+## ADD_EXTRA_CALMING_QUAD
+
+```c
+// 0xFDBF4CDBC07E1706 0xA9419B6D
+int ADD_EXTRA_CALMING_QUAD(float xLow, float yLow, float xHigh, float yHigh, float height);
+```
+
+Only 8 current rises can exist. If rises need to be changed, use REMOVE_EXTRA_CALMING_QUAD and then ADD_EXTRA_CALMING_QUAD again.
+After removing a rise, you will be able to add a rise again.
+
+## Parameters
+* **xLow**: 
+* **yLow**: 
+* **xHigh**: 
+* **yHigh**: 
+* **height**: 
+
+## Return value
+If succeeded to add, returns a rise index that can be used on REMOVE_EXTRA_CALMING_QUAD.
+If failed to add, returns -1 (make sure you don't pass -1 to REMOVE_EXTRA_CALMING_QUAD).
