I believe that the devils roar is too unbalanced, there's no skill when it comes to surviving in the region. This never bothered me too much (because we usually just ignored it) until recently when we were doing an Athena's black powder voyage.
When my friend and I dug up the last remaining stronghold powder barrels, they just blew up without geysers appearing under them and when we waited for geysers to disappear we dug it up and instantly blew up.
Rare, love your game but please find a way to balance the Devils Roar if you keep trying to make us go there.
