I have this armor for when i am soloing my whm, but in a party, I wear the seer tunic*name may be off, lol* the Seer gives you +8 mp and +1 MPH, and if you and your party are both good, you don't really need much HP anyway, lol.
Just did the quest for this today with me as a lvl 30 Sam. I had a 49 whm/blm and a 59 rng helping me. I thought I wasnt gonna finish. At first it started off good I got the first 2 peices and with my whm friend i warped to jeuno and he teleported us back. then it got slow where nothing would drop the key for like an hour or hour and a half. All while the rng was hunting and me and the whm where searching for the chest. We finally manage to get it and i get back with little less than an regular hour left before week is up. I get back to the cave and then is when I get lagged out 3 times. thirty minutes left in I get in and with luck the rng scores another key and finds the chest. I put the gear in storage till I can where it all. Thanks for my ls' help.
My GF bought me this tunic yesterday. Problem is, I'm a BLM and this piece gives an int penalty. I love her gesture though but I'm afraid I'm gonna have to sell it. If only it wasn't for that damn int penalty I could have worn it >.<
The penalty is really negated as the other piece provide bonses to the stats, while others give penalties to the stats that others boost, Although I haven't checked it the all around boost to stats is like +2 to everything.
I think I will quest all the three other pieces and sell them at the AH. In Asura they go for between 50k gil and 70k. This particular item only costs between 10k gil and 13k (this was in Jeuno).
