UPDATED!! This is now an ACTUAL WARNING list!!! I personally am no longer in favor in opening the gate but will not stop anyone interested from using this thread for that reason. 11 out of 24 Nightmares is scary, please try and breed Dreamcatchers in the mean time!
So, as of the Anthrocon 2016 Wyrm Meetup, we have found out that all the Common Types of wyrms need nightmares bred to open the gateway for Abyssal wyrms. I figured I would form a list to....prevent this.....yeah. So if you see that this list needs to be updated, please post in this thread and I will fix it!
Has Nightmare | Needs Nightmare/Has PB | Needs Nightmare/No PB | Exists/Needs to be registered
Common Forest
Leaf Crawler | Plumed Gem Hunter | Horned Wood Borer | Mushroom Gatherer
Crystal
Swirl Snout | Jewel Horn | Resplendent Fantail | Platinum Point
Marine
Hairy Nudibranch | Spiny Puffer | Angler Eel | Bright Darter
Zhong Lung
Qui-Lin | Imperial Fu | Jiao-Di | Gao-Xing
Mountain
Shrieker | Growler | Moss Hoarder | Tunneler
Tundra
Muckmack | Glacier Eater | Snow Snarler | Frostibou
The Nightmares need to be pure bred and not hybrids. If you plan to breed what we are missing, please let me know...so I can tell you its not a good idea...yeah...that....
