normal drag = 150k
ref drag = 3kk
super drag= forgot, most of the time its socketed
COMPOSING A SUPER DRAGON FROM PURELY BOUGHT NORMAL DRAGONS
-------------------------
15 * 150,000 = 2,250,000 + 10,000 = 2,260,000
15 * 2,260,000 = 33,900,000 + 800,000 = 34,700,000
TOTAL: 34.7kk or 34.7million gold
COMPOSING A SUPER DRAGON FROM PURELY FOUND NORMAL DRAGS
------------------------------
15 * free = free + 10,000 = 10,000
15 * 10,000 = 150,000 + 800,000 = 950,000
TOTAL: 950,000 gold, WITH 225 found NORMAL dragon gems(good luck)
in other words, good luck with buying or hunting multiple normal gems
oh and as a side note, reborning will be easier, AND gem prices will fall like the stock market crash
