ID Wands are really common (lots of vendors selling them for 500g-1000g) so wouldn't bother there. Someone mentioned an upcoming change to treasure maps maybe requiring more than 70 cart, so it might be time to just go ahead and max it while you are deciphering maps.
I just unlocked mine, so I'll be maxing it for that. I dont think there is anything useful at 30 points.
Sounds like a plan. Thanks =)
