I've written a fairly basic warlock fightclass. I've included a 'castspell(1, "pet")' spell so the pet casts consume shadows when I am out of combat and PetHealthPct <50. Aside from the fact that I spam this ability during combat, I was wondering is there a way to add an artificial cooldown to the ability to prevent it from spaming...eg. Once used...don't use for at least another 10 seconds. 

Any help or advice appreciated ?

You can use buffcheck

Thanks Smokie, I know how to check buffs on myself but how do I check the pets buffs? 

ObjectManager.Pet.HaveBuff(“name”);
