== Visual representation of drop rates ==
To visualize what this means, here is a graph showing four different drop rates:

! Drop rate !! Color  !! #Attempts for 80% Chance
|-
| 1/10,000  || Red    || 16,000

| 1/20,000  || Orange || 32,000

| 1/30,000  || Blue  || 48,000

So keep grinding, and see the next section for some of the math behind the probabilities of drops.
