Hoarder

You have a compulsion to hold on to everything you find. Who knows when something might prove useful? You gain the following benefits:

• You can now carry twice as much weight as someone else of your size and strength.
• Whenever you would consume an item, and it is not being consumed for casting a spell, roll 1d4. On a roll of 4, you instead do not consume the item.
• You have advantage on Charisma skill checks to haggle for low-level (common or uncommon) rarity items from a trader or merchant.
