All you need to do right now is waiting game.

Stack and rebate.

Protection runes you can get a lot of them from Key rebates.

1050 (for gold essence) you would get 50 or 60 protection runes. Please correct me. I don't remember exact number.

I'd swap that 97% init to pos 1 when it's lvl 10 refine. To lock 1 gold purify is cheaper than 2. That's my opinion.
