Jeebus, Laughlyn. What a jerk.

Samson, use whatever lingo you want. Call it a toon, a character, a person, a Roegdalyn, a taco. Who cares? Some people are going to look for any excuse to be a jerk. Like Laughlyn, apparently. But I wouldn't worry too much about pleasing those people.

As for the Onion Helm, what it does is, when you die, it reduces the amount of time that your toon is affected by weakness. Instead of being "weak" for 3 minutes, you're only weak for a minute and a half. That scales down as you level up, and it disappears entirely at level 10.

Right now, you level up to 10 really quickly. You'll probably have your first job at level 10 by the end of your first set of leves. So, other than the defense benefits it offers, you probably won't be wearing the onion helm for too terribly long.

So I'd say it depends on a) how much time you've already spent in the game; and b) how often you die currently. I did the same thing as you, starting my character and then trying to get the onion helm. I decided it wasn't worth it for me to start over. But it's totally up to you.

Welcome to the game! Hope you enjoy your time in Eorzea!
