Janna
View on Wiki
Excellent (8/10)
Epic Relics
Paid Relics
High Investment Required
Players disagree about Janna's baseline strength. Some consider her early leveling experience difficult and heavily reliant on epic relics to function. While others find her to be an incredibly powerful engine capable of clearing the hardest encounters once fully equipped.
The Infinite Storm
Game Start: Create 7 copies of me in your deck. Champion Spells cost 1 less.
Power: Game Start: Grant a random spell from your deck an item with "-1 cost and draw 1". Create 4 copies of it in your deck.
Power: When you gain the attack token, create a random spell that costs 2 from your regions in hand. It costs 0 and is Fleeting.
Strategy
This build maximizes Janna's spell-slinging engine. Echoing Spirit ensures you draw Janna consistently and provides cheap champion spells, which also prevents decking out during long encounters.
Searing Brilliance offers immediate cost reduction and card draw, synergizing perfectly with her kit. Spellweaver's Symphony generates a zero-cost spell every turn you gain the attack token, allowing you to trigger her cost-reduction powers immediately for massive tempo swings.
Turn One Tempest
Power: Game Start: Drain 5 from the enemy Nexus. Play: If I'm Swain, refill your spell mana.
Plunder: I cost 2 less. I have +1|+1 for each different round you've damaged the enemy Nexus.- Game Start: Create 7 copies of me in your deck. Champion Spells cost 1 less.
Strategy
Designed for aggressive tempo, this build allows Janna to be played on the first turn. Swain's Raven Army damages the enemy Nexus at game start, instantly activating the Plunder cost reduction from Packed Powder.
Once Janna is on the board, Echoing Spirit fuels her engine with discounted champion spells. This enables rapid board development and continuous removal, often leading to infinite combos by the third or fourth turn.
Guardian of Zaun
Play: Shuffle 5 level 2 champions into your deck and double their stats, then draw one of them.
Allied champions have +1|+1 and cost 2 less.- Allied champions have +1|+1 and cost 2 less.
Strategy
This setup leverages Janna's four-mana cost to create a massive tempo swing. Oath of the Guardians shuffles powerful level two champions into the deck, while the dual Star Gems heavily discount them.
Because Janna draws cards efficiently, you can quickly find and play these discounted champions to overwhelm the opponent. This build provides a reliable alternative win condition that bypasses her standard engine requirements.
Value Engine
- Game Start: Create 7 copies of me in your deck. Champion Spells cost 1 less.
Play: Draw the highest cost card that costs less than my base cost, grant it an Epic item, and reduce its cost to 0.- Power: When you gain the attack token, create a random spell that costs 2 from your regions in hand. It costs 0 and is Fleeting.
Strategy
This build focuses on sustained value and board presence. Found Fortune draws and discounts a card to zero, facilitating infinite spell loops and providing critical early-game value.
Combined with Echoing Spirit and Spellweaver's Symphony, Janna can continuously cycle through her deck, maintaining a full board and answering enemy threats efficiently.
Other Relic Options
Boosts the damage of her elemental skills like Howling Gale, turning them into reliable removal tools, though it requires a spell-heavy playstyle to maximize.
Highly effective in monthly challenges where you start with extra mana, though it can clog the hand in standard adventures due to excessive card generation.
This upgrade is considered low-impact because it does not trigger her three-star power, making it a suboptimal choice.
Janna's relic flexibility is high, but she heavily favors items that provide cost reduction, card draw, or spell generation to fuel her engine.
Constellation
Janna is a powerful engine champion who excels at drawing cards and reducing their costs. Her three-star power provides significant cost reduction, acting as an inverse ramp. However, she currently lacks constellation upgrades beyond three stars, which limits her scaling in the highest-difficulty Nightmare adventures compared to newer champions.
What's Updraft?
When you play a cost reduced card, reduce the cost of the top card of your deck by 1.
Eye of the Storm
+1 Starting Mana. When you play a cost reduced card, grant the weakest ally +1|+1.
What's Updraft? II
When you play a cost reduced card, reduce the cost of the top 2 cards of your deck by 1.
Gameplay Tips
- Preventing Deck-Outs
Janna's aggressive card draw can easily lead to milling your own deck. Utilize her leveled-up champion spell to shuffle discounted copies of cards back into your deck, ensuring you maintain a healthy resource pool during longer encounters.
- Managing Board Space
Because Janna can rapidly reduce the cost of her units to zero, board space becomes a premium. Plan your summons carefully and use your own units for favorable trades to make room for more impactful plays.
- Volibear Adventure Counter
Janna struggles significantly in the Volibear adventure. The adventure's power sets all drawn cards to three cost, completely negating her core card-discounting mechanics.
- Deck Optimization
Prioritize cutting Ballistic Bot from the starting deck at healer nodes, as it provides minimal value to her overarching strategy and clogs the hand.
- Navigating Aggressive Encounters
Janna requires time to establish her engine. Against highly aggressive opponents like Irelia or Aurelion Sol, prioritize early blockers and removal spells over pure card draw to stabilize the board before attempting to execute infinite spell loops.
