Where can I find a guide for obtaining penta-melded accessories? I don't have the money for it, so I can't just buy it off the market board, nor do I have a crafter at that level to make it myself.
I guess my first step would be to start getting the items needed to craft these accessories, but I have no idea how to start. I also don't have a crafter at the required levels, so I guess I'd need to find someone willing to make it for me.
Also, should I expect these things to be obsolete by the time patch 3.1 comes out?
See if you can find someone in your FC or your group to make them for cheap. I can't craft them myself, so I ask for people who can. Getting the materials (or buying them off the boards) and then getting someone to make them for you is most likely less expensive than actually buying the finished items off the board whole.
Before you start though, work out what you're going for. Go to Ariyala's calculator and figure out which accessories you want, how many you want, and what stats you want to meld into them (but keep in mind fending accessories don't have space for any secondary stats). I'm assuming you're a tank, and IMO three crafted accessories is a good number for tanks. I run 3 crafted + 2 slaying in Alex Savage.
Once you have an idea of what accessories you want, look up how to make them and get the materials together. Since you can't craft them, this probably means buying or hunting the materials yourself. Then find a guy to craft them for you.
As for the melds themselves, picking what materia to put in is pretty straightforward because of the high stat caps. With an i150 fending accessory, you want 4x STR IV + 1x STR III to max out the strength cap on it. i150 slaying accessories have two main options:
* 4x VIT IV + one other materia of your choice (more expensive but hits VIT cap)
* 3x VIT IV + 1x VIT III + one materia of your choice (less expensive but gets you an accessory 1 short of VIT cap)
Melding also requires a crafter, and since melding can take a lot of tries to succeed, you're pretty much looking at "hiring" a crafter to sit there and try to meld stuff for you for about 10-20 minutes or so, depending on how many materia you're willing to try to meld at once. Bring both the materia and the appropriate catalysts (Grade IV carbonized matter for Grade IV materia, I think) when you do this, since each meld attempt takes a catalyst.
Materia-wise, the meld rates are very low so you want a LOT of materia to try with. This is the most expensive part of the process. If you have spare money, keep an eye out on the market boards and try to buy the materia you want when the prices are lowest (usually during the day on weekdays). You can also spiritbond materia yourself but IMO this is not really practical because you need something like 30-50 materia to meld up each accessory, and spiritbonding gives you a random materia that might not even be what you want. You might be better off grinding money and buying what you want off the market boards.
