Reactors are objects placed around maps that you can click on to collect items. There is usually one reactor on every normal map and multiple on the home map.
Reactors in normal maps are used to collect crafting items like Ancient Coins, Enchant Ingredients, and Food Ingredients. They can very rarely drop energy as well. These reactors take a few hours to respawn after you collect them.
List of ReactorsEdit
These respawn at server time (1 AM UTS) and 12 hours after you collect it the first time.
