Dark: 3 runs at 1.5 drops: 3 legendary, 3 ripper and no knight nor Lilith. 90 stamina for a fully awakened trophy.
Also
Fire: 1 run - 1 naga, 1 starter
Ice: 1 run - 1 legendary, 1 ripper
Wood: 1 run - 1 legendary, 1 starter
Light: 1 run - 1 ripper
Edit: I am staying here until all dark dragons are maxed. 1.5x drop or not.
Edit 2 - Update: Been running it everyday and, at rank 164, it takes two refills to rank up. Already have three spare succubus for awakening and Lilith is already at skill level 3.
Chaos Knight pays a visit from time to time but never drops.
It is a breeze to run with CDKV and friend Green Sonia or 3x leader (ADKZ or Dragon Shogun in my case) and friend Apocalypse or Zaerog (Fagan would need some healing for safe mode).
If I had Tiamat he would probably be max skill already since the legendary drops about once in every 3 runs.
Lil' Black drops almost every run so no need to save any for awakening until you are ready.
