Karax by TheHereticOne

"Karax is of the lowest caste of protoss society, the artisans and worker bees of the mighty race. He treats his engineering craftsmanship like an art form, immensely pleased with his role in society and in the creation of his weaponry and inventions." -Starcraft Wiki

Karax is a Khalai -- the engineers, artisans, etc. of the Protoss society. He excels when dealing with mechanical units and ships, and is extremely proficient at understanding various technologies.

In Heroes of the Storm, Karax is a battle support that relies on shielding his allies as they take damage, enhancing their capacities, regeneration, and allowing them to escape undesirable situations. His shields are extremely potent, but require an ally to be damaged for their full worth to be at maximum efficiency. They are also quite costly in mana. His capacity to regenerate his allies' health is minor, and so it brings other buffs along. However, the beam is constant and has very little mana cost, and should be kept up most of the time. Finally, he brings a shockwave into battle, as his third tool. It targets an ally, and instantly deals a medium amount of damage around this ally, and knocks enemies back. The ability has a low mana cost, and a low cooldown. However, when an ally is chosen for this ability, they gain the ''shaken'' debuff, meaning that if you use the ability on them again before the debuff is gone, the knockback will not occur. The damage, however, will.

As for his trait, Karax brings a sort of ''double trait'' unto the field. Being a worker, Karax was not brought up to fight. However, his engineering skills allow him to compensate for this. Karax has a potent ranged attack that deals medium damage. However, his attack becomes unusable at melee range. When things get in melee range, Karax loses 25% damage against melee range targets, but gains the right to use his robotic arms, allowing him to attack up to 3 targets that are at close range.
The second part of his trait is as follows : Karax has no health regeneration. However, 75% of his health is composed of shields that, after Karax has not taken any actions for 3 seconds, and has not dealt or taken damage in the last 6 seconds, regenerate at an extremely fast rate. Moving, channeling, or taking any action will prevent the shields from regenerating for 3 seconds. Taking or dealing damage will prevent them from regenerating for 6 seconds.
