EX Modifier

EX modified abilities require 25% energy for some and 50% energy for others. By default, you can use an EX ability by holding Shift and pressing the key assigned to the ability you would like to modify. They usually make the ability do something better (with some exceptions like Ezmo's EX M1) or just make the ability do something different that may work out better in certain situations. It is very important to always be aware of your EX abilities for whichever champion you are playing, as not using them ever simply makes you a bad player and you are not using your champion to its fullest potential. Arguably the strongest EX ability in the game is Jade's EX Q. It makes herself and any allies near her immaterial for 2s. This is an example of an EX ability you do not want to be missing out on, as it can easily win you games that you would have otherwise lost. It is also important to make sure you are not saving up energy exclusively for your ultimate every time. In some situations, spending 100% energy on 3-4 EX abilities will benefit you and your team most than just throwing down your ultimate, especially on support champions such as Lucie.
