Only drk and pld use stun for 300 tp. But if u make some counts u can spam stun on different targets and you will run out of tp, talkin about any pvp mode, but since item can only be used in frontlines, you can use that stun every 5 seconds and you are goin to need tp somehow, and you use ite. . These items are also really useful for melees, just imagine a monk or any melee in frontline with these items, he could spam the ogcd it has more often
