AllPowers is not a power. It is a set of powers that gives you some extra abilities on the chat. You must have at least one of each power that is part of the set (the ones marked with a rocket on the powers page) to qualify for it. New powers may be added over time and without notice. You are required to purchase the respective powers to regain AllPowers.
AllPowers currently contains 166 powers, which may take some work for you to keep track of if you're going to purchase them individually. You can click on "Mark All Powers" at the bottom of the powers page to check which unlimited powers you are missing. Limited powers will not be marked due to the fact they are unavailable in the store.
Limited powers required for AllPowers:
AllPowers comes with an extra hat and few exclusive effects for smilies.
To use the Golden Egg Hat, add the following code to your name? (hat#e). To color the egg, you must disable AllPowers first, and then add the color code after #e. For example: (hat#e#FFD800). If you don't have any gifts, you can color it without disabling AllPowers, by replacing #e with #g on the code above.
Adding #allpowers to a smiley code will add a rocket around the smiley.
Adding #w? after #allpowers, where ? can be any character, will remove the rocket and place a ring instead: (d#allpowers#w1).
