Hello!

I want to run underhul elites but I am way too under-geared. From what I looted from egg event I have about 12m budget(not sold any egg yet, this is current lowest auc prices of what I looted)

My current pet is: Gloom(Base), SnS(H), Slag(AA)

My current stats are these:

1- What do you think are the best items I can get?(Not set items since they are extremely hard to get)
I was thinking to get an Immo staff and arcane ring. Don't know about necklace. I'm thinking glint helm and armor too(hexsteel or hexcharge)(I don't want to lose so much crit too)

2- I currently have some weak fury and mind jewels on my gear, should I switch to full mind and slowly build better jewels?

3- Do you think my current pet combo is good? I am thinking to trade my SnS to Immo staff and get toor happiness instead.(Since I am so under-geared looks like I don't deserve SnS happiness yet but is it wise to get Immo staff instead?) I also need arcane ability suggestions for hard elites.

Thank you very much!
