Hello, I have seen this ,NULL command in a macro many times, but I can’t understand what it means, can anyone explain it to me, what it is for and how it works. ---

Usually means nothing as in not available, you can put your name or whatever and as long WoW does not register as an ability still works the same. Now the technique what it is used for is to make a castsequence stop and fail and usually reset on target or combat. The end result is that it will cast only once depending on the reset conditions. ---

Note in some cases “null” doesn’t work the way Lutechi is describing. WoW tries to use an ability like Nullification Barrier. If this happens you need to replace null with something like “iamcompletelyunknown12345”
