Tower defense is my favorite Roblox genre, as players must cooperate to achieve victory. However, to have strong units in Anime Adventures, I had to upgrade them multiple times, which was difficult. Evolving Mythics was a priority, especially with the help of Griffin (Fallen) NPC. For that, I needed to get Eggs of Sacrifice.
The best way to get Sacrifice Eggs fast is to use the Eclipse portals that allow you to organize runs. You can acquire them via Wyndhym Infinite mode. You must be at least level 100 to access it, so be prepared. You'll get several portals per run, so be ready to fight multiple times. You should host runs to get more Eggs of Sacrifice (Periapt of Sacrifice), as you'll get fewer eggs by joining other players' games.
But to be successful, you need other players to join you. If you don't have friends online, invite other players via the Anime Adventures Discord server. When you enter the Eclipse, your task is the same as always - survive all waves and defeat the boss at the end. Don't expect other players to be prepared, so have an air-attack unit ready. You don't want to die at the end because no one has air defense, a lesson I learned for myself.
When you complete the Eclipse run, you'll be rewarded with a random amount of Eggs of Sacrifice. You'll usually get 2-4 eggs if you're a host and 1-2 if you're a guest. To use eggs, you'll need Periapt of the King (Egg of the King) to teleport you to the special area with Griffin (Fallen) NPC. As one Periapt of Sacrifice gives you 0.5% ascension progress, you'll need around 200 Eggs of Sacrifice to evolve Griffin in Anime Adventures. Besides that, you can also sacrifice 24 Mythical units if you have that many you don't need, or combine sacrifice with eggs.
