Location Of T4+ Chests In Molten Heights

Hi!
I recently got my first 100, and being too lazy to make another one, I've decided to start loot-running.

Problem is, I only know the location of two T4 chests in Molten Heights.
Help?

 

They nerfed a bunch, I use glitched slayers run but some people use sky islands

 

I recommend Sky Islands or a place where mobs don't affect the chest.

 

How do they affect the chests in Molten Heights and not in the Sky Islands? I thought it was only based off their tiers and how long they went untouched.

 

I never said chests in the Sky Islands were not affected.

 

I just assumed what I said because of how it was stated. Sorry about that.

Some of the Molten Heights chests were nerfed and that might be why.
