*Update for 8.0 BFA
This weakarura constantly show you how many enemies within 10 yard range (Note: Arcane explosion effective range is 10 yard now)
*This weakaura trigger uses "ItemInRange". It works even if you dont have the item.
*If you want to monitor a different skill other than arcane explosion, you can modify the custom trigger by switching item ID (ex.33069 with purple color as shown in the picture) to another item ID corresponding to the range yard you would like to monitor such as 28767 for 40 yard.
