只想看圖片的可以點進去情報網站看看

黑鐵矮人種族天賦
Dungeon Delver: While indoors, move 4% faster.
室內移動速度提高4%
Fireblood: Removes all poison, disease, curse, magic, and bleed effects and increases your primary stat by 100 for each effect removed. Lasts 8 sec. 2 min cooldown.
移除所有中毒，疾病，詛咒，魔法和流血效果，每個被移除的負面效果將使你的主屬性提升100點，持續8秒，冷卻時間2分鐘。
Forged in Flames: Reduces damage taken from Physical attacks by 1%.
受到的物理傷害降低1%。
Mole Machine: While outdoors, summon a Mole Machine that tunnels through the earth. 30 min cooldown.
當你在室外時，你可以召喚一個鑽地機。冷卻時間30分鐘。 (效果還未確認，個人認為是所有地圖皆可使用的鳥哨)
Mass Production: Items crafted by Blacksmithing are created twice as quickly.
使用鍛造技能製造物品的速度是正常的兩倍。
(要是是使用所有專業技能都是兩倍就很棒)

目前黑鐵矮人挖掘出來可能可以使用的職業有
死亡騎士，獵人，法師，武僧，盜賊，術士，戰士，聖騎士。
聖騎士是在訪談中確認的職業，但是訪談中也有提到新種族是沒有死亡騎士的，而且不知道為什麼黑鐵矮人沒有牧師，也許職業尚未設定完成。

〈鈣片的種類：你知道自己吃的是那一種鈣片？〉

鈣片(Calcium Supplement)，主要的用途，是作為一種補充劑，幫助身體補充鈣質，除了輔助兒童提供鈣質之外，鞏固骨骼，提高骨質密度，促進身體發育，其實，最主要的目的，是為了幫助長者、更年期婦女補充鈣質，紓緩鈣質流失，預防骨質疏鬆，因為這些人士體內的鈣質便會開始流失，因此需要從額外途徑攝取鈣質。

市面上的鈣片，一般而言，主要有三種：

1. 碳酸鈣(Calcium Carbonate)

碳酸鈣(Calcium Carbonate)， 是一種最常見、最常用的鈣片，鈣含量高達40%［念過化學的看倌，不難理解，因為鈣和碳酸鈣的摩爾質量(molar mass)，分別是40.1g/mol和100.1g/mol，因此一摩爾(mole)的鈣和碳酸鈣便是40.1g和100.1g，所以碳酸鈣佔40%是鈣離子］，吸收率約30%。（對！進入消化道的鈣質，並不是全部能夠經過消化道完全吸收的。）

因為碳酸鈣是鹼性的化學鹽，因此，需要一個酸性的環境下，來產生酸鹼中和的化學作用，從而釋放鈣離子出來。化學公式如下：

CaCO3 + 2HCl → CaCl2 + H2O + CO2

因此，碳酸鈣，必須依靠胃酸才能分解鈣離子出來，所以，一般建議餐後服用，透過進食來刺激胃壁，增加胃酸分泌，增加活性鈣的吸收率。

由於碳酸鈣在酸鹼中和的過程中，會產生二氧化碳，所以，不難理解，服用碳酸鈣，較容易會導致胃氣、腹脹、打嗝的情況，對一些消化系統較弱的人士而言，可能會造成腸胃不適的情況。

而且，問題來了：

既然碳酸鈣需要胃酸來消化、分解、吸收的話，那麼，如果是一些罹患胃潰瘍、十二指腸潰瘍的患者，需要服用胃藥，抑制胃酸的分泌，減低胃部的酸性，那麼，在這種情況下，怎麼辦？

念過化學的看倌，一定會知道，與胃酸產生化學反應的，是「碳酸鈣」，而不是「鈣」，與胃酸產生中和作用的，是「碳酸鹽(Carbonate)」，而不是「鈣」。

問題是，天涯何處無鈣片！天下鈣片何其多！要解決這個兩難局面，只需要找一種鈣鹽，不需要透過胃酸來消化、分解、吸收的話，不就是已經解決了問題嗎？

所以，遇到這種情況，我們一般會建議使用其他鈣鹽，例如檸檬酸鈣(Calciun Citate)來取代碳酸鈣，作為膳食鈣補充劑。

還有，一些碳酸鈣的主要來源，是蠔、珍珠、珊瑚這些海產，有時候，需要注意重金屬污染的問題。

2. 檸檬酸鈣(Calciun Citate)

檸檬酸鈣(Calciun Citate)，鈣含量雖然較碳酸鈣低，只有21%，吸收率約30%，但是，吸收不受酸鹼度影響，所以，不受胃酸影響，可以餐前、餐後服用，服用時間不受進食限制，而且藥性較溫和，對消化系統的刺激較輕微，特別適用於一些正在服食胃藥的用藥者使用。

值得一提，因為檸檬酸與鈣結合的時候，不會產生沉澱現象，所以，檸檬酸可以跟草酸進行競爭，與鈣結合，生成水溶性較高的檸檬酸鈣，減少產生草酸鈣的機會，從而預防出現腎結石的風險。

看倌可能會追問：「既然檸檬酸鈣擁有這些優點，那麼，為什麼一開始不廣泛使用呢？」

原因很簡單，因為這是經濟學的問題，不是藥劑學的問題。因為碳酸鈣是天然產品，源自自然界，檸檬酸鈣是合成產品，源自檸檬酸，相較檸檬酸而言，碳酸鈣的成料較低廉、產量較穩定，相反，檸檬酸的原料，是糖，大多源自玉米、甘蔗，一來，需要栽種，容易受到時間、氣候影響，二來，需要配給，有些留作食品，有些留作燃料，所以，檸檬酸鈣的成本較高。

因此，對於一般人而言，碳酸鈣可能是一個較普遍的選擇。

三、乳酸鈣(Calcium Lactate)

乳酸鈣，來源主要是奶類製品，口感較好，三者中鈣含量最低(13.6%)，吸收率約30%，含鈣量較少，含鈣量少，需要服用較大的劑量，確保足夠的鈣質攝取量。

最後，提醒各位看倌，由於鈣的吸收率不高，每次服用鈣片，劑量不宜超過500mg！
