The best money maker I have found, is running reg ToC x 4 per day. With the new option to skip the pagentry, i can knock out 4 in under an hour easily. Disenchant 5xEpics per run = 20 abyss crystals after 4 runs. They sell for ~50g/each on my server so thats around 1k before auction cut. Not bad for less than an hours work.
