A staged power plan from HQ 1 to 30 with calculator links and spending guardrails.
TL;DR
Power = buildings + research + heroes + gear + troops. Never skip Laboratory for vanity buildings.
Stages
Early (HQ 1–15): infrastructure. Mid (16–25): troop tiers and hero stars. Late: specialization.
Calculators
Use HQ and research calculators before every major speed-up weekend.
Whale vs F2P
Whales buy time; F2P buys efficiency. Both need a written plan.
