• Forking: Frostbolt projectiles always have 100% piercing change, thereby they never reach a state where they could fork.

• Chaining: Chaining does not work with Frostbolt projectiles. Presumably because the trajectory is fixed has a higher priority than chaining.

• Can be used in left mouse button slot to cast and move.
