Lucy has long been the trusted source for spell data, but doesnt seem to have undergone any code improvements for a couple years. As such, newer effects and specialized data fields are listed as "unknown" or even incorrect data. However, these are not unknown...only unknown to Lucy. Other spell parsers out there have been updated to correctly display the spell data lines in precision detail. In this respect, Lucy is undergoing the process of being a distant 2nd or 3rd data source.
For example, a level 90 enchanter spell is parsed with unknown data at lucy as:
2: Increase AGI by 129
3: Increase DEX by 108
4: Increase ATK by 114
5: Increase Attack Speed by 68%
6: Increase Chance to Critical Hit by 31% with All Skills
7: Unknown #364 (100/14/0)
8: Critical Damage Mob (8)
Slot-7 should read Increase Chance to Triple Attack by 14%. In this case, Lucy was unable to parse this line at all.
Another example, a level 90 berserker discipline Shared Brutality is parsed by Lucy as:
1: Skill Damage Amount (79)
2: Skill Damage Amount (79)
3: Skill Damage Amount (159)
4: Skill Damage Amount (159)
5: Skill Damage Amount (79)
6: Skill Damage Amount (79)
...when it should be revealing this data:
1: Increase 1H Blunt Damage Bonus by 79
2: Increase 1H Slash Damage Bonus by 79
3: Increase 2H Blunt Damage Bonus by 159
4: Increase 2H Slash Damage Bonus by 159
5: Increase Hand to Hand Damage Bonus by 79
6: Increase Piercing Damage Bonus by 79
Another example of Lucy failing to interpret code, the level 90 enchanter aura (and the 85, 80, 75 versions)
1: Persistent Effect: Unknown Spell
In this case, you are done with lucy. If you went elsewhere you would see: 1: Aura Effect: Mana Reiteration II
Looking further at mana reiteration effect from the other parser we see:
Duration: 18s (3 ticks), Extend: Yes
Max Hits: 6 Matching Spell
1: Cast on Spell Use: Mana Reiteration Strike II Chance: 100%
2: Limit Type: Detrimental
3: Limit Effect: Current HP
5: Limit Spell: Exclude Mana Reiteration Strike II
6: Limit Type: Exclude Procs
7: Limit Max Level: 100 (lose 0% per level)
8: Limit Min Mana Cost: 10
