That sounds like you simply didn't have stealth up. There's been numerous occasions where I ended up in the AoE of the mobs near the adamantite node (due to one of the many other mines forgetting stealth), and I've never actually been hit by it, as long as I was in stealth and interacting with the node.

If for some odd reason (a bug perhaps?), you still get hit, I guess you could always just summon your chocobo to act as a distraction.

As for Deep Vigor, that ability is great for the unspoiled nodes (since those are 6 hits by default), if you're aiming to get 1-2 HQ materials for a craft. It was especially good during ARR as a consistent route of getting the HQ items used to turn in for the higher ilvl gathering tools.
