Will I ever stop breeding bees that can only survive in the nether yet are diurnal? That is the question.
Yes !!
Here's what I do:
1. Enable Binnie's for the Acclimitizer
2. Stick Max. Fert. Princess and Drone (ex. Wintry or Majestic) into Acclimitizer with Ice Blocks, water wax capsules, and lava wax capsules, and let run
3. Stick back in with just sand and let run
4. Take finished Princess and Drone and breed until you have Temp and Humid Both5/Both5.
5. Breed in other handy traits like Faster/Fastest Production (Aer Bees), Cave/Rain/Nocturnal/Diurnal (Rocky), and Shortest Life (Cultivated)
6. Make a ton of Princesses of some species that doesn't have any further mutations
7. Take 1 Nether-loving drone and breed with Princess from step 6.
8. Take hybrid and breed with another pure Princess from step 6.
9. Repeat until you have hybrid with all desired traits
10. Breed hybrid princess and hybrid drone until you have pure Princess and Drones of Nether-loving species (from step 7)
I only have to cycle steps 8 and 9 about 4 or 5 times. Step 10 takes another 4 to 5 times. I use Oblivion Frames if available. Otherwise, I use Necrotic Frames (use Thauminomicon recipe, not NEI recipe).
