That's a nice tip. Here is an extension: as long as you don't ask the fire elemental to help you with the ice situation (pick the "take you leave" line as soon as possible), the 3 elemental will stay here, meaning you can come back here every level up for some orange item shopping.
Also a good tip! While we are at it, if you are up to unlocking things like this early so you have options on every level up - there is a certain vendor near
**minor spoiler**
Hunter's Edge - its an undead skeleton/ghost vendor that sells insane stuff, always legendaries etc - if you can get to him early via invisibility - just get the Phantom Forest waypoint and you can teleport here every level up and check his goods too. Combine this with your tip, and its a decent way to actually have a chance at better / tailored loot for your party if you are opposed to save scumming for loot.
