Ive gotten where I just use my lancer retainer for quick ventures primarily and my miner gathers whatever resource is selling well. So the DoW one is my RNG gamble one and the DoL one I can make 10-15k gil per venture based on the level she's at. The more interesting quick venture items I've gotten include a Tonberry Chandelier which I sold for a few hundred thousand gil (since my private room has a Morbol chandelier already) and I got some Manor/Stone Vigil furniture which were in the 100k+ range on marketboard but I kept because I figure gil comes and goes but particularly valuable furniture that comes my way via that route has more meaning to me vs if I bought it.
