In Castle Age on Facebook, the GUI hides certain buttons based on your current stats. If you only have a certain amount of stamina for example, it will hide the higher stamina attack links from you, but they’re still there for you to use if you wish.
I found a site that helps you easily create the links to use. All you need on your end is the monster link, which is easy assuming you’ve already engaged the monster.
1. Pull up your Monster page in Castle Age
2. Right click the Engage button. If you’re using IE7 select Copy Shortcut, in Firefox it’s Copy Link Location, and in Chrome it’s Copy Link Address
3. Go to http://dndworld.com/ca/ and paste your link in the box, and click the Call Buttons button
4. This will create a page of buttons for each major type of monster since the script doesn’t know what type of monster you gave it. Look for the monster group and simply click the button for the type of attack you want to use.
