かまどがレベル30に達すると、建物は通常の資源ではなくファイアクリスタル(FC)と精製ファイアクリスタル(RFC)で強化されます。本計算機は、かまど・大使館・指令センター・医務室・3つの部隊キャンプ・兵法学院の建物をFC1からFC10まで上げるのに必要なFCとRFCを合計します。
ファイアクリスタルの強化は高コストで、大量のSvSポイントを与えます。各建物の正確なFC/RFCコストとSvS報酬を計画すれば、ファイアクリスタルの日に合わせて強化を行い、イベントスコアを最大化できます。
Select each building (Furnace, troop camps, Embassy, Infirmary…) and its current Fire Crystal level. If a building is still below Furnace 30, use the Buildings calculator instead.
Choose the FC level you want to reach, up to FC10. The calculator adds up every step in between, for one building or several at once.
See the total Fire Crystals and Refined Fire Crystals required, plus the SvS points the upgrades will award.
Compare the cost to your stock and schedule the upgrades for the Fire Crystal day of SvS to turn the spend into peak event scoring.
Each Fire Crystal upgrade awards State vs State points based on the materials it consumes. As a rule of thumb: SvS points ≈ Fire Crystals × 2,000 + Refined Fire Crystals × 30,000, plus a bonus for the construction speed-ups the upgrade represents.
Example: an upgrade costing 500 FC and 40 RFC gives roughly 500 × 2,000 + 40 × 30,000 = 1,000,000 + 1,200,000 = 2,200,000 SvS points before the speed-up bonus. Because each Refined Fire Crystal is worth about 15× a raw Fire Crystal in points, upgrades that lean on RFC produce the biggest spikes on Fire Crystal day.
