Strange, I was in r same situation last week, they died it for me I'm 3 days.
The was an issue with them being unable to read my email (no one else had the issue) so they have be a broadsword address to send to.
And the only skill you really need is cartography and magery.
Is a melee Treasure Hunter feasible then or would the spawn be too tough?
I agree with Merus on each point, with a caveat for magic equipme…
