Need a little help dealing with Actionmanager

So I am trying to finish up a ninja routine and I ran into a problem with my mutilate condition. I want to make sure that it will not break my combo chain. All the conditions work except for Armor Crush. I tried LastSpell.Name == "Armor Crush" and also the LastSpellId == 3563 but mutilate never casts after armor crush. However it can cast after Dancing Edge, Shadow Fang, and Aeolian Edge. Any help is much appreciated.

Code:

	public static async Task<bool> Mutilate()
	{
	
		if (Me.CurrentTarget.HasAura(AuraBook.ShadowFang) && !Me.CurrentTarget.HasAura(AuraBook.Mutilate, true, NinjaSettings.MutilationClip) && (Actionmanager.LastSpellId == 3563 || Actionmanager.LastSpellId == 2251 || Actionmanager.LastSpellId == 2255 || Actionmanager.LastSpellId == 2257))
		{
			await Spell.CastSpell("Mutilate", () => true);	
			
		}
		
		return false;
	}
