Fork

Fork is a behavior of projectiles that causes them to split into two identical projectiles when they hit a target.

Mechanics

When a projectile forks, it splits into two identical projectiles that continue travelling at 60 and -60 degree angles from the projectile's original trajectory. A projectile can only fork once unless it is supported by the awakened fork support gem.

Only one projectile behavior can be applied each time a projectile hits a target. Fork has second priority for projectile behaviors, preceded by #1 pierce, and then followed by #3 chain and #4 return. This means that if you had pierce, chain, and fork supporting the same skill, it would first pierce to it's maximum number of pierces, then fork, then chain to its maximum number of chains.

Projectiles apply their on-hit effects to each target they fork on or otherwise hit. For example, Essence DrainEssence DrainSpell, Projectile, Duration, Chaos, AoE
