I am retiring a character, and the DM has given me permission to carry out the following actions, so long as I can physically "carry" them.
The cleric is attempting to withdraw 500,000 gp from a group vault (see How will this much GP impact our game? for how that loot haul came about) and haul it a decent distance away. He is looking to do this by himself, and on foot, or at most, a steed or two, depending on the species of pack animal. He is a level 6 War Cleric and has no spells to do so, and also has no magical holding items on his person, but could possibly purchase some.
Is there anything that holds more than the bag of holding, as it only holds 500 lbs, and 500,000 gold pieces weighs 10,000 lbs, as it is 50 gp to every pound. I understand this may be a bit broad of a question, but basically, I'm hoping to have him walk maybe 100 miles, with simple camping gear, and standard equipment. He is a humble man, and tends to be a loner (he has a negative charisma score.) I'm simply looking for the best means to transport 500,000 gp while attempting to remain on foot, inconspicuous, and be able to trek through the woods. So, there can't be an armed guard, any carriages, or multiple people.
My DM is open-minded and is allowing the use of magic items to do so, which opens my options a bit. I'm just looking for creative ideas, or something that someone can help me that I may have missed. The best thing I've found so far is 20 bags of holding, which still seems a bit much for one dwarf trying to travel as humbly and inconspicuously as possible. His strength score is a 13, by the way, and he has access to Enhance Ability.
Also, I wouldn't mind having him use a pack animal or two, so long as they can trek across large amounts of forested and rocky terrain.
This is the largest bank in the capital city, so there should be the possibility of converting the gold into platinum. I'd rather keep it gold in order to increase the utility of the currency, as he won't have an easy way to convert it back once he reaches his destination, a deserted monastery way off in a desolate region.
He would prefer to walk as he has lived among the mountains all his life until our recent adventuring months.
I no longer have our group's portable hole as another party member has it.
Also, my Dwarven cleric specifically requested that the withdrawal be made in 500,000 gold pieces. I suppose he could also have some of it withdrawn as platinum or gems, but this will have to remain a small portion, as there will be no banks where he is going.
