Just threw out some ideas for other items that work well depending on your team and or opponents.
-bottle, are you controlling mid?
-Vanguard vs Perseverance - what are you up against and or what roll are you playing.
-Desolator can easily be filled in for heart of Tarrasque especially if your pushing towers.
-Does anyone on your team have Vladmir's Offering?
Good luck and happy haunting.
