How It Works

I think the last unknown, represents a boolean if the conditions should be and'ed or or'ed together (it's only set for entries with more than one condition).

The "comparator" field seems to determine how to compare the values, what I've noticed so far, from what's available in the DBC file at the moment:

  • 2: Seems to be <
    • Used in Compare as: Requires more [compareColor] gems than [gemColor] gems.
  • 3: Seems to be >
    • Used in Compare as: Requires more [gemColor] gems than [compareColor] gems.
    • Used in Value as: Requires at least [value + 1] [gemColor] gems.
  • 5: Seems to be >=
    • Used in Value as: Requires at least [value] [gemColor] gems.

Type: Value

Example: 
Swift Skyfire Diamond
+24 Attack Power and Minor Run Speed Increase
Requires at least 2 Yellow gems
Requires at least 1 Red gem

Matching DBC entry (id 31):

gemColor:     {3, 2, 0, 0, 0}
unknownValue: {0, 0, 0, 0, 0}
comparator:   {5, 5, 0, 0, 0}
compareColor: {0, 0, 0, 0, 0}
value:        {2, 1, 0, 0, 0}
unknown:      {1, 0, 0, 0, 0}
  • Requires at least (2) (Gem Type 3 = Yellow) gems
  • Requires at least (1) (Gem Type 2 = Red) gems

Type: Compare

Example: 
Bracing Earthstorm Diamond
+26 Healing Spells & 2% Reduced Threat
Requires more Yellow gems than Blue gems
Requires more Red gems than Blue gems

Matching DBC entry (id 34):

gemColor:     {3, 2, 0, 0, 0}
unknownValue: {0, 0, 0, 0, 0}
comparator:   {3, 3, 0, 0, 0}
compareColor: {4, 4, 0, 0, 0}
value:        {0, 0, 0, 0, 0}
unknown:      {1, 0, 0, 0, 0}
  • Requires more (Gem Type 3 = Yellow) gems than (Gem Type 4 = Blue) gems
  • Requires more (Gem Type 2 = Red) gems than (Gem Type 4 = Blue) gems
