Best place to use Brazier of Elemental Summoning?

[VII]

There was another thread asking the same question, but it's closed and last post was in 2014.

Was wondering, now with 2018's patches out there what the best place to pop one of these potions would be. I'd be playing a cleric, and probably would get level 5 before popping it, so I'd have 'med' learned first.

Befallen? Upper Guk? I know the elemental is only lvl 12, but worth the ask.

Thanks fellas!
