I've been one tricking Zilean for maybe a year and a half now, and I haven't ever majorly changed my build. I feel it's efficient, but I wonder what other Zilean support mains build on him.

I've changed support items, but my core build is pretty much the same. My current build is:

• Eye of the Oasis. Used to be FQC Sightstone for around a year which was inefficient as my support items took 2 slots instead of 1, and I only bought FQC for the slow/facecheck power, but I have both of those in my kit.
  
• Lucidity Boots
• Morellonomicon
• Luden's Echo
• Liandry's Torment. Not really sure what's a good 5th item. I just recently starting building Eye of the Oasis so I haven't thought of what good be a good last item.
• Pinks for the last slot.

Does anyone ever change up their builds depending on the comp? I feel like I always go this build regardless of the comp.
