Macro without GS, little problem


I use this macro on my demo but the immolation is launched every 5/7 seconds. I would want to launch it every 10 to 12 seconds. How could i do that?

#showtooltip Chaos Bolt
/targetenemy [noharm][dead]
/castsequence [nochanneling] reset=8 Incinérer,Incinérer,Incinérer,Incinérer,Immolation
/castsequence [nochanneling]reset=.03 Conflagration,Conflagration,Conflagration,Conflagration,Ame sombre : Instabilité
/cast [nochanneling]Trait du chaos
/cast [nochanneling]Verrou d’ombre

Try something like this:

#showtooltip Incinerate
/targetenemy [noharm][dead]
/cast [nopet]Summon Doomguard
/castsequence [nochanneling] reset=10 immolate,Incinerate,Incinerate,Incinerate,Incinerate,Incinerate,Incinerate
/castsequence [nochanneling]reset=.03 Conflagrate,Conflagrate,Conflagrate,Conflagrate,Dark Soul: Instability
/cast [nochanneling]Chaos Bolt
/castrandom Shadowburn
/cast [nochanneling]Command Demon
/use 13
/use 14
