I just witnessed how powerful this ability is!!! Currently I am at Diamond II rank and this is what happened: 
All of the range attack missed! And since the rule set is oppurtunity all of the range attacks was focused on NAGA! In addition this was possible because the ruleset includes enrage witch brought NAGA's speed to 11!
So that's it guys! I just want to share this awesome experience! Stay safe and keep grinding!
