requires a bonded pack animal, the ability to cast spells and a pet ball.....this is Siege, make that 2 pet balls, keep one in the bank just in case the original is misappropriated.
Choose hunting spot, choose place to stash gold (and maybe pet ball?) out of sight except by use of circle of trans, or object handles. Preferably on the edge of the spawn area.
Hunt till the stash hits pack animal limit.
Ensure spawn is away from stash, summon pet, load it. Tell pet 'all stay', invis pet.
Leave dungeon, gate to bank, summon pet, tell pet 'all follow me' and move one step to reveal it. Unload pet.
I just brought 80k out of Ice Dungeon, Felucca, Europa this way.
