This glitch works with v1.01. Use the following glitch to duplicate as many Quicksilver Bullets and Blood Echoes as desired. Start a new game, and create a second character. Teleport that character to Hunter's Dream, and place a Pebble in storage. Exit the game, and return to the title screen. Select your main character, then teleport to Hunter's Dream. Sell everything in your storage to the merchant in the area. Place the item to be duplicated in your storage. For example, place Coldblood in storage for Blood Echoes. Place as many Pebbles as desired into storage, and they will be converted into that item. Repeat the process as many times as desired.
