Experience comes from real game events: each point of confirmed damage grants 1 XP and a successful work action grants 10 XP. Your profile shows level, total XP and the remaining amount to the next level. The first profile unlocks a second profile slot at level 50 and a third at level 80.

Headquarters, Military Power and Research are separate skill levels. Training starts with a GOLD or GEMS cost that grows with level and completes when its duration ends. Only one training runs at a time and the cost is charged up front.

Premium shortens training duration without changing the cost. With Premium you can automate a selected skill; when balance or membership runs out no new step starts, while the running training still completes.
