I have always heard that there is an order that you have to follow after building the spectral op.
Before spec op
water-stone-fire-wind-chrono - in any order
After spec op:
What would happen if you found an egg out of order and built the op? Would that make getting other eggs impossible?
I ask this because in the realm I am playing in, while I was still under protection, I was attacking a level 8 plain to get the Chrono Core but a Helio egg dropped and I built the op. I had already built the spec op and had the ice and the sunken op's up but I did not have the Amber Crest egg (still don't) or the Chrono Core. I have been hunting both the Amber Crest egg and Chrono Core for weeks now with hundreds of attacks looking for them... I have gotten Helio Dragon armor hitting plains while looking for the Chrono Core. I also was told that the drop rate for the Chrono was much higher than all the rest making it easy to find.
I think there is something wrong with my account now that I found and built the Helio op out of the order it is listed in. Can anyone inform me if this is true or if I have just been extremely unlucky at finding the Chrono and the Amber Crest?
