Chances of Success

In Ji Dian Station, your chance of success comes down to the sum of two numbers -- your roll plus your challenge number. The challenge number is the sum of all that stats in your favor minus everything against you (including difficulty of the challenge).

There are ten possible ranges of challenge number from -5 up to +4.

• -5 = 2% Nigh Impossible
• -4 = 8% Dangerous
• -3 = 17% Very Hard
• -2 = 28% Hard
• -1 = 42% Below Average
• 0 = 52% Average
• 1 = 72% Easy
• 2 = 83% Very Easy
• 3 = 91% Trivial
• 4 = 97% Automatic
