armor: When an item with a certain rarity is used as a recipe ingredient, the resulting crafted item may have a chance to obtain the same rarity. The chances will go this way:
For the chances on what specific rarity (uncommon, rare, epic) can be obtained, we'll assign numbers to each rarity for simplification (1-uncommon, 2-rare, 3-epic). Say for example: if you crafted a beastmaster garb using basilisk studded leather [epic] and quilted armor of endurance(V) [rare], using the simplification above, the average of the two items is 2.5 [(3+2)/2 = 2.5], and since 2.5 is between 2 (rare) and 3 (epic), meaning that the crafted beastmaster garb has a 50% chance of receiving either rare or epic rarity.
