Sorry to break it to yah but you out of luck, the pet you have not gonna to help that much since it only gave tainted gem and the shard. It better if you have the Nulgath Birthday Pet which it have all in one items for farming, tho the price would be around 1500 Acs. Of course if u play the game for 3 years you would get 1500 for free, just like me xd. But the pet is seasonal item so when it gone, it gone forever until the next birthday.
You still can farm it without the birthday pet, but it will take way way more of your time. There a lot of bots that you can use for farming it normal way (without pet, etc) but you gotta have to search on ur own since the bot probably like 3-4 years old. It better if u make ur own
Just focus on 1 item at a time and lookup the most fastest way to farm it. When finish, go to another item and repeat. That how Ive been doing before purchase the pet
