Dragadt, all i did was copy paste the multicast macro and plugin my spell names. the tooltip changed to the right spell, but then when i pressed it, nothing happened, and the CC would not do anything.
i highlighted the main target macro, copied, pasted in my macro interface i removed the spaces before the / so that it wouldnt spam it in chat, and i plugged in my spell names, i left the " " too. i just replaced what you wrote in red. so heres one i made :
#showtooltip Death Grip
/script SpellName=Death Grip;
/script MultiCastMT=1;
