Diana was recently mayor and I spent around 4 billion coins on summoning eyes. In the past, I was unlucky with dropping any dragon pets. I wanted to change that.
I had both farmed and bought summoning eyes. I was able to grind about 20 eyes an hour. I could fill a double chest every 2 and a half hours. The gear I used was Superior armor with a clean Daedalus axe, and a Mythic Black Cat.
Dragon Loot
I got pretty lucky with dropping dragon pets, however, I got unlucky with the rarity.
I got lucky with some of the pets getting them within 30 summons of each other, while others was more than 250.
In the end I profited around 1.1 billion coins. The Dragon Pets I got pretty much paid for all the summoning eyes, while the rest of the loot was profit.
I had a lot of fun summoning dragons. After looking at the profits, I will probably do more dragons next Diana. I will be doing dungeons and grinding summoning eyes in the meanwhile.
