Xin'Jin, the Void-Child is not a champion in League of Legends.

Portals
Chaos Portal and Void Portal are linked to eachother. Players within 1200 units of either portal will gain vision of the other and in a 350 unit radius around it. The location of the linked portal will also be indicated by a visual effect between the two.

Champions or their skill-shot projectiles coming within 150 units of either portal will be teleported to the other. The portals' facings determine the direction objects entering one portal will exit from the other.

Enemy projectiles that are teleported in this way can damage enemy units they strike, (Xin'Jin will receive the credit for the damage, but the projectile's effect will be determined by its caster's stats).

Portals will dissipate after teleporting one object, or more if they were created using Stability (though this may require multiple casts of the other portal).

Strategies
Xin'Jin is a highly mobile melee mage whose portals can be combined in a number of powerful ways.

Most directly, Chaos Portal can be used to deal moderate to high damage across a wide area, clearing waves quickly and causing a sizeable armour and magic resist debuff on enemies during team fights, and sizeable defensive buffs to allies. Void Portal can be used to slow enemies and haste allies, keeping Xin'Jin in melee range or allowing her to escape.

Almost as directly, casting both Chaos Portal and Void Portal in the same location will trigger Xin'Jin's Annihilation passive, combining the damage and defensive debuff of Chaos Portal with the slowing effect of Void Portal across a large area - a powerful start to any team fight.

But the real challenge in playing Xin'Jin comes from the link between her Void Portal and her Chaos Portal. Whilst both are active, enemy champions, allied champions, any of their skill-shot projectiles, and Xin'Jin herself, will teleport automatically between them if they enter a portal.

At its simplest, this provides Xin'Jin with a way to quickly cover distance to enemy champions or away from them, possibly across walls, by creating one portal in front of her and one where she would like to move, and entering the nearest one herself. But this simple combination can also be used as a pull, by placing one portal near to herself and her allies, and creating the second portal directly on top of an enemy champion, forcing them to be teleported to Xin'Jin and her allies, or can be used to send enemy skill shots back at their caster by placing one portal facing the enemy (perhaps in nearby brush), and using the second portal to block the enemy's attack - or even using the portals to attack from unexpected angles with your own team's skill-shots - Blitzcrank's Rocket Grab, for example, can reach through the portals and pull an enemy champion back through!).

Using Stability, these combinations can become extremely dangerous or lifesaving, allowing (for example) a long series of projectiles to be reflected, or allowing every single member of Xin'Jin's team to instantly teleport from one location to another.

Xin'Jin's ultimate, Wormhole, can be used to rescue an ally as a very-long-range but very-long-cooldown version of Thresh's Dark Passage, or to teleport herself much like Twisted Fate's Gate, or indeed to allow any single nearby ally to teleport in this way.

For her most devastating combination, Xin'Jin can cast a Stabilised Void Portal at her current location, then travel a huge distance by using Wormhole to teleport herself, and then casting a Stabilised Chaos Portal, enabling every member of her team in her previous location to join her in her new one.
