with all the new weapon ideas and how in the description of the Space Races how it says a ‘rare artifact’. I came up with an idea that could incorporate both. I usually skip the Daily, weekly Challanges and Space Races but to make heros want to do them more often, when you defeat the final boss of a Daily challange you collect a 75% chance of a common item and a 25% chance of an Uncommon item that you can put towards building new weapons. The higher of difficulty level the greater the chance of an Uncommon to rare item.
Weekly challenges give you a rare - legendary.
space Races ultra rare to Legendary.
