Ah? - Chang'e Item Build for Mid(Dealer) and Solo(Bruiser)

BUILD FOR MID
This is big power build, just for better healing and better damaging.
Start with Sands of Time and Spellbook and 1 Multi Potion

1. Standard Mid Full Build
Shoes of Focus will provide you CD and also mana.
Book of Thoth will provide you a lot of mana and power.
Divine Ruin will give you plat-pen and anti-healing. Even if they don't have a healer, Anubis or Hades and so on, I recommend to build it because of hunters' lifesteal. Of course, if you want to have more CD and don't see any healers in enemy team, you can build Spear of Desolation .
Rod of Tahuti will boost your damaging and healing. You can heal 25% more to an ally who has lower than 50% health. Also it has 10% pen. But even if Hirez remove penetration, I will still recommend to build this.
Rod of Asclepius increases your healing and also provides movement speed and health. It was bad item before, but it is good after healing changes.
Pendulum of Ages will make you synergy with Book of Thoth.

2. 6th Item Option
Sometimes your support or solo will build Caduceus Shield or Rod of Asclepius. As you know, you don't have to build same aura items unless it is antiheal aura or Mystical Mail. So, here are options:
Warlock's Staff gives you 10% penetration and bunch of health, also mana. It is just for penetration and synergy with Book of Thoth and Pendulum of Ages because of mana. You don't have to try to stack it. And you shouldn't build it if they have Qin's Sais or other Health's percentage items.
Doom Orb gives you movement speed and a lot of power. It is a still good item.

3. 7th Item Option
This means item you should buy after you sell your shoes.
Obsidian Shard will be niche and popular pick because of % penetration.
Soul Gem can be good, because of health, lifesteal, CD and additional damage.
Ethereal Staff gives you 20% CCR and more health. Build it if they have hard CC-high- health monsters.
Chronos' Pendant will give you 20% CD and CD redcution. Actually I recommend this item for 7th because you'll build Divine Ruin usually, that means you'll have only 20-30% CD.

4. Relics.
Blink Rune is always good. But if enemy mid is Nox or Anubis, of course you should pick Purification Beads first.

==========================

BUILD FOR SOLO
This is for lane-stability and tanking at late game.
Picking a mage as a solo means we lose a potential tank that enemies have. So you should build tanky and brusier to help your teammate as a solo laner.

1. Starter Items
Sands of Time for 10% CD and MP5. I recommend this.
Tainted Steel for healer enemies. But it is not that good item for early-mid lane sustain, so I don't recommend it. Let's wait until they buff this item.
Vampiric Shroud for health and mana sustain. It is quite good but I still recommend Sands of Time.

2. Common Items in both Physical and Magical
These are essenstional for Guardian Solo build, either.
Shoes of Focus will provide you CD and mana.
Breastplate of Valor will provide you big CD and mana.
Void Stone will provide you 10% penetration in your 1 and 3.

3. Defense Items
Tyrannical Plate Helm will give you 20% CCR, which is most important and minion enhancement. I recommend to build this after you get Bov so you get full CDR
Lotus Crown is a good option because of MP5 and team-protection. So I will say sell Tyrannical for late game team fight.
Contagion and Pestilence for Anti-heal Aura. Even if your support bought other antiheal aura, you should buy it still.
Ethereal Staff for Big health and 20% CCR.

4. Penetraiton Options
Void Stone is a basic option that I recommend. But, if they have a lot of healer or, your mid is too good so you don't have to care bout their mage, build Divine Ruin
You can build Warlock's Staff just for health and pen. But I don't recommend it and Ethereal is better option in solo.

5. 7th Item Options
Chronos' Pendant will be basic choice. As you see, you don't have enough power. That means you'll deal tiny damage.
Mantle of Discord for more tankiness. This can be niche pick.
Gauntlet of Thebes is situational. You see, someitmes your support doesn't build Gauntlet because they have Sentinel's Embrace and other Aura protection items. Adding Gauntlet will help you and your teammate a lot, so build it if your support didn't.
And as I said above, when you have this late game, sell Tyrannical and buy Lotus Crown for your team fight.

6. Relics
1st Relic
Teleport Glyph is popular choice for solo, since it gives you movement speed after you arrive at your tower.
Purification Beads for Hercules, Anubis or other gods.
Blink Rune is good pick for Chang'e, so you use it when you do surprise-multiple-ult on your enemies.
2nd Relic
Magic Shell to help your teammates.
Phantom's Veil for Odin.
Cursed Ankh for Vamana or other healer team.

Idk I should call this tips, but I'll write it if you never played Chang'e before.

Set your 2 as Instant Casting.
3-1 combo is good.
Be a lane bully. Pretend to clear minion and deal damage to your opponent.
Chang'e mid's 1~2 level's damage is quite good. Make a low health or kill your enemey mid as you can.
Chang'e's(lol) role in teamfight is one: land your ult at least 3 people. It's not that hard than you think. Just be careful.
Spam your passive. But sometimes he will stuck somewhere and doesn't move. Go back to base and this bug will be fixed.
