Thalyssra by Sonario

Thalyssra's presence causes leylines to form throughout the map. By going near them, Thalyssra gains ability power and mana regeneration. If Thalyssra visits a leyline for more than 10 seconds, she will enchance her next primary ability with the leyline's power, granting it bonus effectiveness.

Sends a wave of arcane missiles towards an enemy hero, homing in on enemies hit (prioritizes heroes), but dealing reduced damage for each missile beyond the first that hit the same enemy hero. Deals double damage to minions.

Leyline Mastery: Leaves an arcane echo that targets the nearest random hero with the ability again after 3 seconds.

Zaps target area with a quick jolt of arcane energy. If it hits at least one target, the jolt will continue towards the next possible target, zapping everyone around it. If a target has been hit by Spark of the Arcane, a jolt cannot be passed through that target.

Leyline Mastery: Now has infinite bounces, and can bounce to targets that are already jolted, but it has a 1 second delay after each bounce.

Passive: Whenever Thalyssra gets a takedown on a hero, or is nearby 5 minion deaths, she gains a stack of warpwalking, indicated by a bar near her health. She can cast this ability to consume the stacks, teleporting a small distance and granting her movement speed, increased per stack of Warpwalking.

Leyline Mastery: Thalyssra can recast this ability again, granting her 50% of the movement speed bonus for 50% of the duration, but the teleport remains the same.

Thalyssra grants an allied hero some of her arcane energy for 1 minute. If the hero is to take fatal damage, instead a forcefield will form, knocking back all enemy heroes, minions and mercenaries, dealing damage to them if they come near. The allied hero is put in stasis for 5 seconds, while he recovers 50% of his health and mana.

Withers a target enemy hero. The target deals reduced damage, has reduced movement speed and health, cannot take any healing, and is stunned for 1 second after the effect expires. Lasts 3 seconds.
