Create an alt, level to 16, leave tortage, powerlevel in Keshetta till 30, then spend 50 offline levels. Repeat. This can be done in about 4 hours total if you have a decently fast group for the Keshetta powerleveling.
Running out of time though, so you better get moving fast if you want to actually use them before Funcom steals them away from you like the greedy *people* they are.
