Electro Core
Late-game resource for Electro Level upgrades (past Lv.30)
Electro Core is a special resource that becomes available once your server reaches 70 days old. It is required to upgrade buildings beyond Level 30. These upgrades are called Electro Levels.
Each Electro Level is divided into five upgrade stages. For example, to go from building Level 30 to Electro Level 1 (EL1), you complete stages 30-1 → 30-2 → 30-3 → 30-4 → 30-5. After the fifth upgrade, the building becomes EL1.

3,560 Tip. Save cores for Chief’s Office and academies first if
you need HQ progression — they cost the most per sub-level. Hospital and
Command Center are the cheapest of the seven.
