World - Crystal Collecting

• There are Green Crystal mines of different levels on the map. Players may seize a mine to collect Green Crystals. This is the main source of getting Green Crystals for most players.

• Over time, Green Crystal mines will gradually move towards the center of the world map.

• To collect crystals, players need to attack and defeat the NPC at a crystal mine. In case you lose the fight, your troops will return to the city immediately and 1 crystal collecting opportunity is deducted.

• Heroes restore 1 crystal collecting opportunity every 8 hours.

• Each hero may have up to 3 crystal collecting opportunities.

• The crystal collection speed is determined by the crystal mine level. The higher level a mine is at, the faster you can collect.

• The max number of crystals you may collect is affected by the crystal coefficient. The bigger the crystal coefficient, the more you can collect.

• The actual max number of crystals you may collect is determined by your remaining troops. The more soldiers you have left, the more crystals you can collect.

• Max number of crystals you may collect = Hero's crystal coefficient * 1.5 * (1 + Crystal mine collecting bonus + VIP level crystal collecting bonus) * (Number of surviving soldiers/Number of dispatched soldiers + 0.1).

• Real-time crystal gain = Hero's crystal coefficient * 1.5 * (1 + Crystal mine collecting bonus + VIP level crystal collecting bonus) * 0.1 + (Collecting time * Collecting speed).
