Xeldarith is a elite swordsman among Demacia's ranks. He was then faced with a task befitting his caliber, somehow succeeding, but had to sustain heavy wounds and leaving him with only a handful of his men. Returning to Demacia with his spirits downed, he then sought ways to further improve his skills, so that no one will die anymore because of his weakness. On one occasion, he was able to meet and ask Lux so that she could teach him her craft, light magic and the likes. Lux agreed, and thus in a span of a week or so, Xeldarith mastered to form swords of light at his disposal. He could have studied for more, but he did not want to bother the lady any longer.
After a long while, he went back to the fields of battle, leading Demacian troops to victory. He gained the reputation of a 'Sword Saint', due to his ability to form swords of light and bring up unexpected assaults with it. He also used it to instill fear in his foes; wielding a sword of light in hand, dashing through the battlefield with speed and grace, and making the sky rain with blades on rare occasions. Xeldarith then knew that there was only one place left where he could truly gauge his skill, and that is in the League of Legends.

Precision Cutting: No longer has cast delay. Damage scaling is increased. The critical will not be available while Precision Cutting is on cooldown.
He can be tanky in fights because of his third skill. Building items like Thornmail can give him more survivability. One can also try giving him Warmog's Armor or Frozen Mallet for increased health. He can then benefit from high health with Atma's Impaler for increased attack damage or Maw of Malmortius if you're often focus-fired or the one who's initiating.
He can be built in many ways, since he scales from AP or AD. One can also opt to make him have high attack speed with Phantom Dancer
