The exact ratios are 151:44:4:1 for Common/Uncommon/Rare/Legendary rewards in Warframe. If a category is missing (like Rare) then that gets folded into Common. So the distribution would become 155:44:1 for Common/Uncommon/Legendary. That's how DE does it. That's how I can say "Legendary always = 0.5%."

Look at the drop table Rngd444 linked. Add up all the values in each *category* and you will see it comes to 75.5%/22%/2%/0.5% (which is 151:44:4:1) There is a RNG that rolls 1-200. That determines the category. Then a separate RNG rolls an equal chance against everything in that sub table.

Stating that it is "Legendary" means that there is a 0.5% chance to roll something in that table. Since there's only 1 result in that table, that's the chance- 1 in 200. (aka 0.5%)

Rngd444, how are you arriving at the values 30.44% and 1.243% ?
