I'm new in d3helper I trying to use 3 different computers and in VMWare with windows 10 and 8 but same issue for me: all conditions are ignored and my skill is casted in a loop. I trying to use with Wizard ou WD but same problem.
You should use the condition: isMonsterSelected Currently you would spam until oom as long as 3 or less enemies are within 50y. If you check the checkbox it will cast if MORE OR EQUAL to 3 are present within 50y. But without isMonsterSelected (= mouseover an enemy) you will cast it even if no enemy is selected.
