Hi, can anyone suggest a proven way to get seals quickly, I need to roll a few hundred because I wanted to do the first approach, I need to get some and I also don't have a bit to create, is there an easier way to get hundreds or possibly seals that are later processed?

Craft them and hope to get a viable 100.
When you run t100 all seals that drop are also t100 (obviously) for further keys
