Hello, everyone. I want a buff to display a number in order to show how many charges an ability has remaining. I tried to do so by using an Slow Tornado ability with green colors for the buff display, but the main problem was that aura's buffs take a few seconds to update when leveled up, so I was thinking in creating multiple abilities with the same two first letters for the integer part and the last two for the level (SK01, SK02, SK03, SK04...). I created a string and an integer variables to make my idea work, but I got stuck in the process as I'm not too skilled in JASS. Which functions should I use for what I want to do? Thanks in advance.
