Allagan Tomestones

[Nutz]

If you just hit 50, I'd concentrate firstly on capping poetics, secondly on running ST as much as possible, and really nevermind soldiery gains -- you'll want to get to at least 1300 to buy Rowena's tickets. Combine those with an unidentified allagan tomestone, which should be pretty simple to get from ST and you've already got a good weapon. Make sure you also have a sands of time available to use on said weapon. With luck you'll have at least i100 on the left side from ST, so I'd actually suggest buying a ring with poetics. After that I'd fill in the left side, but that's me. After buying your soldiery weapon, gradually upgrade your accessories to soldiery and upgrade them with oils of time. After that swap out left side ST items for soldiery items and upgrade them with sands of time, or buy poetics items for the left side.

EDIT: Sorry if this incorrectly assumes you can get into Syrcus Tower. If not, aim for that. Obviously any drops that are upgrades should be worn and upgrading accessories is the fastest way to increase your ilvl.
