Winter Orb

Winter Orb is a channelling skill (a spell). Channeling the skill charges up an orb, which fires icy projectiles to deal cold damage enemies, which target the ground to deal area of effect damage.

Skill functions and interactions

While Winter Orb has the Projectile keyword, testing shows it appears to gain no benefit from the Fork Support, Pierce Support, or Chain Support gems, even though the Active Skills window shows them as compatible. Firing projectiles in a nova with Sire of Shards causes multiple projects to launch spread out as expected but land not exactly the same distance away from the caster.

Math

Projectile hit rate

Base projectile rate at stage 1 with no cast speed is .625 per second.

The first stage does not gain projectile frequency. Therefore 10 stages gives (9 X 15) = 135% increased projectile frequency. The plus 2 maximum stages helmet enchantment adds 30% projectile frequency.

All cast speed modifiers are additive with the increased projectile frequency. Therefore a 10 stage winter orb with 100% cast speed has (135 + 100) = 235% total increase projectile frequency.

100% more projectile frequency will double your projectile fire rate while channeling.

Example: 10 stages, 100% cast speed. Currently being channeled.

• (.625 x 3.35) = 2.1 (2.1 x 2) = 4.2 per second.
