If you really can't wait, keep creating, power-leveling, raiding and deleting same-class characters. Other than that, I highly recommend getting to Rank 4 with Eris, so you can turn Radiant Energies into Shards.

if you absolutely want to get to 32, you need to run the full raid with 3 characters, dismantle any duplicate armor/weapons, and convert any energies your get to shards. or, you could just wait it out and get the materials you need over a couple of weeks. make sure the raid armor you have is worth upgrading. they all have random intelligence/strength/discipline. Make sure you have the stats you need before wasting shards on them.
