Forge Points, or simply referred to as "FP" or "F.P.", are used to research various Technologies as well as to Trade with other players. It will cost you 1 Forge Point to fulfill a trade offer. Note that only the player that accepts the offer will have to spend 1 Forge Point; the player that created the Trade offer won't. In guild-only trading, no forge point is needed. Forge points are also used to upgrade great buildings.
You will receive 1 Forge Point every hour up to a maximum of 10. Should your Forge Points reach the maximum of 10, the timer will stop and start over from 1 hour once you have 9 or fewer Forge Points.
Therefore it is highly recommended that you spend your Forge Points as often as possible.
Buying Forge PointsEdit
It costs 50 diamonds for each expansion. You may buy the first Forge Point for 100 Gold, and thereafter the price will increase by increments of 50 Coins per point. In the diagram below, the cost of FP has risen to 11850 Coins, from the original 100 gold.
Forge Point Purchase Cost FormulaEdit
In determining how much X amount of Forge Points will cost in terms of gold (Y), use the formula:
Y = X(initial amount to purchase)+50(X(X-1)/2)
For example. I need 23 Forge Points to finish researching a technology. My starting cost is 3000 gold.
- Y = X(3000)+50(X(X-1)/2)
- Y = 23(3000)+50(23 x 22 / 2)
- Y = 81,650 Gold Coins.
The equation is built upon the fact that purchasing a FP increases by +50 gold everytime you purchase one.
