About the new Explorer/Adventurer rings for those wondering.

I heard a rumour you can get the ring then delete the character and keep the ring, is that true? b/c I don't have a lot of space on my main acc, and it would save me some NX down the road if I don't need an extra char slot for Dual Blade. I doubt it'd work like this, but it's worth checking right?

Yep, the ring is indendant from the character, so You can delete the char and keep the ring as long as you put the ring in storage first.
