Use item on mob while in combat

[ZaneMcFate]

I'm working on a quest where you must kill mob A, then mob B spawns, you must use an item on mob B, then kill him, then the objective is complete. How should I go about this? Any logic I have used so far simply kills the mob and never gets around to using the item. I can only assume this is because I am using an out of combat tag when I should be using something else. The segment:

	<If Condition="GetQuestStep(67042) == 1">
		<UseItem NpcIds="2988,30" ItemId="2001384" QuestId="67042" StepId="1">
			<HotSpots>
				<HotSpot XYZ="-201.2393, -62.14565, 356.6518" Radius="80" />
			</HotSpots>
		</UseItem>
<!--		<Grind while="GetQuestStep(67042) == 1" PostCombatDelay="2.5" grindRef="WhatEvilLurksInTheHeartsOfGolems"/> -->
	</If>
