Additional Information
The Storm is coming in.

  • Ball Lightning disjoints projectiles upon cast.
  • Storm Spirit is invulnerable during Ball Lightning.
  • Storm Spirit can turn, cast spells, use items and attack during Ball Lightning.
  • If Storm Spirit runs out of mana while traveling he will stop immediately.

Know that the activation cost hasn't changed. It's still 15 + 7%. All that's changed is the distance cost, from 10 + 1% to 12 + 0.7%. So if 0.3% of your max mana is less than 2 (i.e. your max mana is less than 667), the new cost is higher than the old, but otherwise the new cost is lower.

The improvement in cost approaches 30% as distance and manapool grow without bound.

Storm Spirit becomes enveloped with energy, losing his physical form, and travels until he depletes his mana or reaches his target. While in this form, he deals damage to nearby units based on how far his electrical form has traversed. Damage, speed and area of effect improves per level.
