Storm Spirit

Raijin Thunderkeg, the Storm Spirit, is a quick and energetic ranged intelligence Hero who wields the elemental power of lightning. 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 to sustain his ultimate. Although relatively weak from the get-go, if he gathers enough power through kills and items, he can quickly become an unstoppable force of nature.

Tips

 * 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.

Trivia

 * Storm Spirit's hat was added to Team Fortress 2 on the 18th August 2011 as Storm Spirit's Jolly Hat.
