Here is how to make quick cash in stratholme using disenchanting. First of all, you need to have at least 250 enchanting. Second of all, you need to be 70. Here are the steps:
1. Go to the back entrance of stratholme.
2. Go inside and sneak around most of the mobs.
3. Kill the first two mini bosses closest to the back entrance. (Forgot their names sorry.)
4. They both drop at least 1 blue item. These DE into large brilliant shards. They sell for around 8g on most servers and I no this isnt alot but it stacks up good.
5. DE the items and go back outside. Reset the instance and do this over again 5 times. (Because you can only run instances 5 times per hour.)
So doing this strategy you will make around 80g per hour.
