1% cdr = $30
1 魔穿 = $34.3
1 物穿 = $40
5% cdr = $150 + 上限+5%
(3+0.3/lv)雙穿 = $223 + $22.3/lv
(3+0.3/lv)魔穿 = $103 + $10.3/lv (5等追平)
(3+0.3/lv)物穿 = $120 + $12/lv (3等追平)
雙穿勝
符文價值(取最便宜之符文來比較)
1紫 = 2.81顆小符文(取最超值小符文之平均)
1% cdr = 0.4 紫
1 雙穿 = 2.72 紅 ((1/0.9+1/0.62)/(0.9+0.62)=1.79)
1 魔穿 = 1.15 紅
1 物穿 = 0.78 紅
5% cdr = 2紫 = 5.62
(3+0.3/lv)雙穿 = 5.37 + 0.54/lv (紅)1等打平
(3+0.3/lv)魔穿 = 3.45 + 0.35/lv (紅)5等打平
(3+0.3/lv)物穿 = 2.34 + 0.23/lv (紅)14等打平
雙穿勝
結論：
雙穿(預知)－混傷一波型 (前期贏線、6等一套帶走)
CDR (智慧)－純傷技能型 (算血、操作有自信，少一點傷多5%cdr)
Ex: Lv6 齊勒斯 (此時雙穿4.8)
Q 7 W 14 E 13 R 130
5%cdr Q 6.65 W 13.3 E 12.35 R 123.5
減少 0.35 0.7 0.65 6.5
兩者效益，端看個人理解與操作
