The only really common ID I started with was Skyly... whoop de do, not like I don't see 500 of those online everyday [/exaggeration]. I've got a Bluefull in Ultimate and a Viridia that's slowly climbing so I've got the uncommon IDs ready to go. I find Oran is a very rare sight as well... it's hardly ever even mentioned.
That's because Oran has few good things to hunt online. It's good if you're into piping... since you can get Syncesta and Aura Field with it. Not too much else... most items you can get with Oran have better drops in other IDs. :ermm:
And if you're into piping, a high level HUnewearl can pipe indefinitely for free since she gains enough TP whilst you're piping...
I know that one first hand... but I've only ever piped Poison Lilies for God/HP upon God/HP. Eight so far... maybe I should get nine... *thinks*
I used my HUnewearl for the process so my TP was always near max.
lol ZOMG save your measly 300 odd meseta for a telepipe!
...
I find it easier to pipe with telepipes because it's faster, mind you, depends on how long you spend in the shop buying and how long you end up piping for.
Well if you're going to use telepipes... do yourself a favour and buy 10 telepipes at a time and drop them in the general area where your pipe will appear. Get around 100 or more there in total. People always say they have too much mesta... what's 35000 going to hurt?
EDIT: Oh and Anti... Ryuker is the faster way. Just cast Ryuler the second you show up on Ragol and it should be cast by the time the enemy appears.
Well, I don't think I'm going to get online anytime soon, so I'll make a Redria. Also, I only pipe with telepipes if I have a lot of extra Meseta. But why spend it when you can pipe forever without spending anything?
Yeah Redria is a good all around ID, so its good for finding rares for a Hunewearl and other classes too. Go for it!

What about Oran for Aura Field and Syncesta? Purplenum has a nice Lavis drop, so you don't need to worry about that as much.
