Shadowbolt

Overview
Using this ability will heavily slow your character for the duration of the cast time, during this period ability can be cancelled. After cast time is complete without interruption, projectile will be released from position of your character in the direction of your cursor. After hitting enemy unit projectile will disappear. Hitting objects will also destroy projectile and deal damage to object hit, if possible.

After the Gloomrot update, Blood Magic Abilities apply. Also, the magic damage was reduced from 200% to 180%.

Strategy
Shadowbolt is a spell with heavy damage, but also a long cast time that makes you vulnerable to enemy spells. The ability is great when combined with some kind of crowd control, like stun from, incapacitate from Slashers' Camouflage or a effect. Best cast after an enemy has used their defensive spells.
