For the items I chose a couple of new items and combined it with some AP items as well to get the best Lissandra support build. Your core items include the new Evenshroud and Winter's Approach items as well as boots and the reworked Demonic Embrace. Evenshroud it a great item because like Leona you will be up in thier face, CCing them allowing your team to do more damage to the enemy. Along with that you have Winter's Approach/Fimbulwinter, a new tank mana item built from Tear of the Goddess and was actually ported over from Wild Rift. The items is great because it gives lots mana, HP, and a shield when you slow or immobilize(hit an enemy with hard CC). After building boots you will build a great newly reworked item in s12, first itroduced in s11, Demonic Embrace. Demonic Embrace is a much better item now because it give you AP based on total hp and works amazing with this build because all 3 items give a ton of HP as well as most of the final items you will build. For the final items all you need to build are items that are good against the enemy comp you are against to become even more tankier.
