Chests and keys
What is in every chest, with the guaranteed item and the odds the game shows.
Every chest shows what it guarantees before you open it. Each chest always holds one gear piece of its own rarity; only the extra pieces are rolled, and the game shows their odds on the chest. A Common key turns up in 20% of games, an Uncommon key in 7% and a Rare key in 2%.
