I have a (very) long running 3.5e game with a group of friends that is about to wrap up before the end of this year. Every character is level 19 and we got here the hard way, using XP count from stat blocks. Suffice to say we've made a lot of money and optimized our builds to a considerable degree.

On my character sheet right now, inside of my Big Ass Bag Of Holding™️, I'm just going to copy and paste this directly (gold count is the cost of the item in case I ever want to sell these - don't worry, I won't) :

Full Pimp Suit Ensemble :

25000gp, Rod of Splendor (gives charisma bonus +4 and an extremely swanky suit)

1000gp, Embroidered silk and velvet mantle with moonstones

9000gp, Gold cup set with emeralds

inside of

2500gp, Mythril bound mahogany treasure chest

I've only had one opportunity to actually use this so far, but it was brilliant, and I plan to pull it out again after we wrap up this campaign and I take over the late lich king's kingdom on the moon. I think it'll look nice for my coronation.
