Storm Spirit

Raijin Thunderkeg, the Storm Spirit, is a quick ranged Intelligence hero who wields the elemental power of lightning to travel and gank around the map. Static Remnant creates an electrically charged immobile clone of himself to shock enemies upon contact. Electric Vortex binds an enemy to a certain location, pulling it slowly and Overload uses the excess charge whenever Raijin casts a spell and throws it on the next attack, zapping enemies in an area. Finally, Storm Spirit's signature move is Ball Lightning where Dtorm engulfs himself in spiritual lightning, sacrificing its own mana and dash to an area in any part of the globe with high electric force. A capable ganker in the early stages of the game due to his abilities, he transitions into a highly mobile and aggressive semi-carry, provided that he has enough mana and mana regeneration to sustain his ultimate. Using Static Remnant with its very low cooldown and mana cost allows Raijin to repeatedly cast it should he be close to the enemy and to attack them with a charge from Overload while Electric Vortex chains them in place and unleash its next attack again with Overload. The instant cooldown of Ball Lightning allows Raijin to spam it whenever he wants to, travelling around the battlefield and triggering Overload, boosting its next attack. Like the storms, he needs time and energy to build up and once it has been developed, he is ready to strike, disturbing anywhere on the field with lightning and thunder, zapping foes with surprise and get away safely.

Tips

 * Static Remnant is an effective nuke useful for pushing and triggering Overload attacks, the overloaded attacks are useful for assaulting and heavily slowing enemies (even for just a brief amount of time).
 * A common tactic most people use is to cast his ultimate, Ball Lightning, at minuscule ranges to trigger his Overload passive after which he attacks his target then repeating the steps again, potentially giving Storm Spirit's slow a higher duration.
 * Though essentially it is not orb-walking, it does have a similar process.
 * A very common combo Storm Spirit uses to nuke down lone heroes is to ambush them with Ball Lightning, then applying Overload > Vortex > Overload > Remnant > Overload > Ball Lightning through them to dodge their retaliation > Overload > Escape if enemy has not died. This will greatly injure most heroes, and kill those foolish enough to be walking around alone with weakened HP.
 * Another alternative would be to use ball lightning > overload > vortex > remnant > overload > then just normal attack and use ball lightning to chase enemies when out of range. When engaging heroes like Earthshaker/ Vengeful Spirit, a wise move would be to use ball lightning after vortex is over since the enemy would most likely cast a stun first which storm would be able to dodge.
 * When engaging a group of heroes, Storm Spirit can actually, although at a risk, be the first one to engage them, followed by several allies already behind him to back him up. This strategy can make enemy heroes blow most cooldowns on Storm Spirit while he can simple run away with Ball Lightning, disable a hero with Electric Vortex, leave a Static Remnant behind and pave the way for allied heroes and their counter initiation.
 * Note: Storm's Ball Lightning deals a reasonable amount of damage when it is maxed out, so using ball lightning from a far distance will deal huge damage to the enemy.
 * While in Ball Lightning, you can use items like Shiva's Guard to bring a dazzling yet deadly cold storm which follows around while rolling on. Great for initiating and crippling enemies, along with Overload, escaping away is most unlikely. You can also cast Static Remnant for farming or pushing, or just show some amazing power.

Trivia
