Let's make something clear before we start.

　　1.Sigil of DK are powerful,the existance of Sigil made the battle totally different.

　　2.Sigil of the Vengeful Heart and Sigil of Awareness affect different spells,but they all common used in rotation.

　　3.Can be shifted in battle.

　　4.That triggers GCD(Tip.3)

　　With the upper basement,we may imagine:We can higher our DPS by ensure our spells been sigal-reinforced.But changing sigals by manual made workload bursted,and the rotations may be confused when in mistake.So maybe we can use some macro to lessen ourwork.

　　Here's the method of macro made with a frost talent as an example.

　　General rotation were just like: Plague Strike==>Chill Touch==>Blood Strike*2==>Obliterate==>Frost Strike*N==>Obliterate*3==>Frost Strike*N triggers howling blast.

　　You need to change to Sigil of the Vengeful Heart after all the rune used up,and turns to Sigil of Awareness after runic power's empty.Tied sigals to Obliterate and Frost Strike are your best choice.

　　Sigal changing macro

　　Macro1

　　/cast Obliterate

　　/equip Sigil of the Vengeful Heart

　　Macro 2

　　/cast Frost Strike

　　/equip Sigil of Awareness

　　Command of sigal changing should written after spells,or that may eat up a GCD.And you need to wait until the former GCD's over before you cast an other,or you'll found your spell's fail to cast and only the sigal's changed with a GCD's wasted.

　　Frost rotation can be fixed like:Plague Strike==>Chill Touch==>Blood Strike*2==>Macro 1==>Frost Strike*N-1==>Macro 2==>Obliterate*2==>Macro 1==>Frost Strike*N-1==>Macro 2

　　You can also put Sigil of the Frozen Conscience and Sigil of the Dark Rider into your rotation
