Buying Rare/Ex-Gear

Hello!

Since I'm too lazy I want to try to buy Dynamis-gear instead of farming it.
But since they're Rare/Ex how you can buy them?

Do you join the Dynamis-group, watch TV and when you're lucky the group gets the drop and I can lot for it?
Or do you even have to fight/heal/whatever in the group and/or just pay for the chance to get the item in 1 run?

Thanks in advance!

Depending on who you go with they can do a variety of things but um they might say to you to wait outside with a glass and only enter if it drops (so you don't waste your time in dynamis if it doesn't drop) or they might ask you to come in from the very begining to just stand afk and lot, or they might ask you to help them, to be honest its up to you.

You're the one paying for the goods. All they have to do is deliver it. The conditions on the transaction can be up to you! ^^


Edit: Oh but no matter what they'll probably ask for the gil first and then you can cast lots :D
