Etherian Mana is used to summon Towers and Traps in the Old One's Army event. It has a high chance to be dropped by all of the Old One's Army event Monsters. Each wave will produce Etherian Mana in multiples of ten - after receiving a starting amount of ten when activating the Eternia Crystal, each wave will produce either 20 or 30 Etherian Mana. Each rod-casted defense tower costs 10 Etherian Mana/Use, so conserving Etherian Mana and developing a strategy is key to the event.
This item will disappear after the invasion has ended, along with all event enemies.
- It is possible to keep the Etherian Mana by placing it in a chest (do not open it again if the event isn't in progress or it'll be lost) before the Old One's Army event ends.
- In the game code, prior to 1.3.5, its name was "its an ammo technically!". Because the actual name was stored in a separate file, this wouldn't display.
