Mechanics tags

What the theory layer reads from Jaina's kit. Each tag shows the ability or talent text that produced it; curated notes cover play-style traits the text cannot show.

Crowd control

Root
Ability Ring of Frost “After a 1.5 second delay, create a Ring of Frost in an area that deals 310 damage and Roots enemies for 3 seconds.”

Defense and mobility

Block
Talent Frost Armor “Additionally, every 10 seconds, Jaina gains 75 Physical Armor against the next enemy Hero Basic Attack, reducing the…”

Ability Improved Ice Block “Activate to place Jaina in Stasis and gain Invulnerability for 2.5 seconds.”
Ability Ice Cold “Activate to grant Jaina Protected and Unstoppable for 2.5 seconds.”
Physical Armor

Damage and macro

Area damage
Ability Blizzard “Bombard an area with 3 waves of ice, dealing 142 damage each.”
Ability Summon Water Elemental “The Water Elemental's Basic Attacks deal 62 damage, splash for 25% damage and Chill.”
Ability Ring of Frost “After a 1.5 second delay, create a Ring of Frost in an area that deals 310 damage and Roots enemies for 3 seconds.”
Armor shred
Talent Northern Exposure “Enemies damaged by Cone of Cold have their Armor lowered by 25 for 2 seconds, increasing their damage taken by 25%.”
Burst
Ability Cone of Cold “Deal 220 damage and Chill targets.”
Ability Frostbolt “Deal 184 damage and Chill the target.”
Curated note Frostbite makes Chilled targets take 50% more damage from her Abilities, so one Frostbolt into Cone of Cold rotation takes close to half of a squishy Hero's Health.
Mana hungry
Curated note Blizzard costs 90 Mana and her rotation is spammy, so without Arcane Intellect or Regeneration Globes she runs dry in long fights.
Poke
Ability Frostbolt “Deal 184 damage and Chill the target.”
Ability Blizzard “Bombard an area with 3 waves of ice, dealing 142 damage each.”
Ability Cone of Cold “Deal 220 damage and Chill targets.”

Play-style traits

Vulnerable body
Curated note Only 1365 Health and no dash; until her quest unlocks Ice Block she survives dives purely through positioning.
