==Use==
Blizzard deals light damage to a single target. At low levels it is the only single-target spell that grants and maintains Umbral Ice, which significantly increases MP regeneration. Use of Blizzard is thus essential at these levels to recover MP after expending it in the Astral Fire phase. is an area of effect (AoE) alternative to Blizzard, but requires four or more targets to deal more damage.
While under the effect of Astral Fire, Blizzard will remove all stacks of that effect instead of applying Umbral Ice, thus requiring two casts to enter Umbral Ice. can be used to more quickly switch phases.
Once becomes available it mostly replaces Blizzard and Transpose, as it can bring the Black Mage to Umbral Ice III in a single cast. Blizzard can still be used to get an extra MP tick out of Umbral Ice before switching to Astral Fire as it has superior DPS and MP efficiency to Blizzard III, but even this niche will be outweighed by once that becomes available.
===PvP===
In PvP Blizzard is instant cast with no MP cost, and now switches to Umbral Ice in a single cast even if the user is in Astral Fire. Umbral Ice functions differently in PvP as it now lowers cast and recast times by 20% and no longer regenerates MP. To compensate, Blizzard itself now grants 2000 MP when used.
As an instant cast spell that activates the global cooldown (GCD), Blizzard can be used to weave abilities that are off the global cooldown (oGCD), such as , in between spellcasts.

==Behind the scenes==
=== Final Fantasy XIV (version 1.0) ===
At the launch of the original Final Fantasy XIV, Blizzard was a Conjurer spell that dealt ice-elemental damage to all enemies within an area of effect. The spell was available at rank 1, cost 3 action points to set, and had a MP cost of 10. 
When the spell was transferred to the Thaumaturge class in Patch 1.20, Blizzard had its area of effect removed and became a single target spell instead. When used the spell would inflict ice damage to the target and also inflicted the Heavy status.
