Check this site db.irowiki.org and search for those items, if they appear, then they're 99% legal/legit in iRO. If not, cross your fingers dude.
And if iRO allow those items in our server, what will the iChaos community feels? Just my two cents worth though before any useful comments will hit me again.
Even some items that only iRO doesn't have (yes, kRO, jRO, and bRO - Brazil have a very few of them) has been nerfed, not just some pRO only items.
Alright thanks again for your opinion sir Mikael! You guys may now calm down. Ahahahahahaha
