Version. 56 we get Macros which assign 3 skills a common button that uses them one after another when you use the Macro Skill, you are allowed to name your macros and shout them when you use them. there is a glitch which allows you to cuss with macros please do not exploit this glitch because it will work against the very thing we are working for in HouseHlaalu. These macros do not make the 3 individual skills one skill but uses them in the order you set them up in. Here are some helpful Macros from me and our guild mates.
