Background[edit | edit source]

Main article: Druid

Druids harness the vast powers of nature to preserve balance and protect life. With experience, druids can unleash nature’s raw energy against their enemies, raining celestial fury on them from a great distance, binding them with enchanted vines, or ensnaring them in unrelenting cyclones. Druids can also direct this power to heal wounds and restore life to fallen allies. They are deeply in tune with the animal spirits of Azeroth. As master shapeshifters, druids can take on the forms of a variety of beasts, morphing into a bear, cat, storm crow, or sea lion with ease. This flexibility allows them to fill different roles during their adventures, tearing enemies to shreds one minute and surveying the battlefield from the sky the next. These keepers of the natural order are among the most versatile heroes in Azeroth, and they must be prepared to adjust to new challenges on a moment’s notice.^[1]

Hero Power[edit | edit source]

Shapeshift is the druid's Hero Power. It grants the druid a +1 Attack for that turn, and +1 Armor, allowing them to tackle enemy minions head-on, or even attack the enemy hero directly. It is useful for removing smaller or weakened minions, and can be combined with effects like Claw or Savage Roar to increase damage output. When no other options present themselves, Shapeshift is a decent fallback option, combining the accumulation of a small amount of Armor with the opportunity to deal small amounts of damage to the opponent's hero or minions.

NB: while the Armor gained by Shapeshift stacks with other Armor effects and is not lost at the end of your turn, the Attack bonus is only available for the turn the Hero Power is used.

Replacement Hero Powers[edit | edit source]

Justicar Trueheart's and Sir Finley of the Sands' Battlecry and Baku the Mooneater's Start of Game effect will replace Shapeshift with Dire Shapeshift.

Malfurion the Pestilent will replace the current Hero Power with Plague Lord when he replaces your hero.

Untapped Potential will replace the current Hero Power with Ossirian Tear once the Quest is completed.

Unique mechanics[edit | edit source]

The Choose One ability allows the player to choose one of two options upon playing a card. Choose One effects are only available to the druid class, and provide powerful versatility, allowing the player to choose between effects depending on their chosen strategy and immediate needs. For example Ancient of War can become either a 10/5, or a 5/10 Taunt, representing powerful aggressive and defensive approaches respectively.

Through cards like Nourish, Wild Growth, Grove Tender, Innervate, Darnassus Aspirant or Astral Communion, the druid also has unique access to accelerated mana gain. In an extreme example: the player can use two Wild Growths to achieve 10 Mana Crystals two turns earlier than usual, gain up to 2 more Mana Crystals (for a single turn only) by using two Innervates; this would allow a possible 12 available mana upon a druid's eighth turn. Using Astral Communion the druid can gain 10 mana crystals on the fourth turn, at the price of discarding their hand.

Gameplay and Strategy[edit | edit source]

The druid class offers an immensely versatile style of play; capitalizing on the Choose One mechanic is essential to make the most of the druid's potential. Druids are often considered to be the class least affected by RNG, due to the versatility of their Choose One effects, helping the druid to change strategy mid-game. This can also help in countering the randomness of the matchmaking process.

Druids have the unique ability to increase their mana growth, chiefly through Wild Growth and Nourish. At the cost of losing tempo, druids can use the extra mana to play bigger minions earlier than other classes. This can allow druid decks to focus on more expensive minions without losing during the early game. If your opponent doesn't have any cards to nullify heavy-hitters (such as Polymorph or Execute) or lots of low-cost Taunts, this can potentially allow you to shave off half or more of their Health in the first few turns.

Contrasting their ability to play large minions, druids are also effective at summoning many small minions. Token Druid decks build a large board of small minions with cards like Wispering Woods and Living Mana, then follow it up by buffing them up with board-wide buffs like Mark of the Wild or Savage Roar to get huge value and burst damage off of them, while Soul of the Forest makes their board harder to clear.

A druid is unafraid of taking the offensive himself; the Hero Power Shapeshift allows him to deal low damage, while also gaining Armor to make up for resulting Health loss, or simply to slowly build up his defences. This is useful for early game removal or simply an extra point of damage when it's needed. Claw, Bite and Pounce take this aspect further.

Druids have powerful damage spells that excel at removal and burn tactics; Wrath, Swipe, Starfall and Starfire. The combination of these cards means continuous board control. Spell Damage can make these even more potent, with Swipe being the premier example as both single-target and board-wide damages are increased. They can combo these spells with Malygos to create a devastating finisher, a process with involves cheating out its very high cost with combos like Aviana and Kun the Forgotten King or Flobbidinous Floop.

Druids are also very resilient, thanks to their ability to both heal and gain Armor. Cards like Crystal Power, Hidden Oasis, Branching Paths, and Ferocious Howl lets them take a beating until they can draw their most powerful cards. Luckily, druids also have one of the best card draws in the game, in the form of cards like Ultimate Infestation and Juicy Psychmelon.

If Armor isn't enough, druids also employ Taunt minions to fend off attacks. Spreading Plague summons weak but sturdy Locusts to block off attacks, while Hadronox resurrects an entire army of Taunt minions to protect the druid.

Druids have a small synergy with Beasts, although much less so than hunters. Cards like Druid of the Fang, Mark of Y'Shaarj and Witching Hour reward the druid for using Beasts in their decks, and there are a few druid Beasts, mostly the result of transform effects.

In Mean Streets of Gadgetzan, as part of the Jade Lotus they gained the ability to summon Jade Golems. Using their Jade Idols, druids could draw out their entire deck and replace them with more Jade Idols, summoning bigger Jade Golems until they reached critical mass. Even if they did start out weak, their array of defensive cards kept themselves protected until they could stem the tide of battle.

Spells[edit | edit source]

See Spell.

Name / Desc	Rarity	Class	Cost	Description
Innervate	Free	Druid	0	Gain 1 Mana Crystal this turn only. Some druids still have flashbacks from strangers yelling "Innervate me!!" at them.
Moonfire	Free	Druid	0	Deal 1 damage. "Cast Moonfire, and never stop." - How to Be a Druid, Chapter 5, Section 3
Claw	Free	Druid	1	Give your hero +2 Attack this turn and 2 Armor. The claw decides who will stay and who will go.
Mark of the Wild	Free	Druid	2	Give a minion Taunt and +2/+2. (+2 Attack/+2 Health) Not to be confused with Jim of the Wild.
Healing Touch	Free	Druid	3	Restore 8 Health. 8 Health, no waiting.
Savage Roar	Free	Druid	3	Give your characters +2 Attack this turn. What do they roar? Nobody can quite tell, but it sounds like "Elephant Macho Breeze". It's probably not that, though.
Wild Growth	Free	Druid	3	Gain an empty Mana Crystal. Grow your own mana crystals with this Mana Crystal Growth Kit, only 39.99!
Swipe	Free	Druid	4	Deal 4 damage to an enemy and 1 damage to all other enemies. When a bear rears back and extends his arms, he's about to Swipe! ... or hug.
Starfire	Free	Druid	6	Deal 5 damage. Draw a card. Balance is important to druids. This card is perfectly balanced.
Lightning Bloom	Common		0	Gain 2 Mana Crystals this turn only. Overload: (2) Curiously, this plant never blooms in the same place twice.
Adorable Infestation	Common		1	Give a minion +1/+1. Summon a 1/1 Cub. Add a Cub to your hand. Some cards are strong by sheer power; others draw strength from love.
Crystal Power	Common	Druid	1	Choose One: Deal 2 damage to a minion; or Restore 5 Health. Often used as healing crystals, but also good for throwing at people.
Nature Studies	Common	Druid	1	Discover a spell. Your next one costs (1) less. "I have a first edition! Go ahead, count the rings."
Strength in Numbers	Common	Druid	1	Sidequest: Spend 10 Mana on minions. Reward: Summon a minion from your deck. One minion, two minions... tree minions!
Worthy Expedition	Common	Druid	1	Discover a Choose One card. This isn't where I parked my mount.
Power of the Wild	Common	Druid	2	Choose One - Give your minions +1/+1; or Summon a 3/2 Panther. Never look a panther in the eye. Or is it 'Always look a panther in the eye'? Well, it's one of those.
Rising Winds	Common	Druid	2	Twinspell Choose One - Draw a card; or Summon a 3/2 Eagle. Do not talk to me or my chick ever again.
Wrath	Common	Druid	2	Choose One - Deal 3 damage to a minion; or 1 damage and draw a card. The talk around the Ratchet Inn is that this card is too good and should be a Legendary.
BEEEES!!!	Common	Druid	3	Choose a minion. Summon four 1/1 Bees that attack it. Right before CEEEES!!!
Blessing of the Ancients	Common	Druid	3	Twinspell Give your minions +1/+1. Arguably the cutest blessing.
Bogbeam	Common	Druid	3	Deal 3 damage to a minion. Costs (0) if you have at least 7 Mana Crystals. Some think the mysterious bright lights in the bog are alien invaders, others think they're just swamp gas. Turns out, it's just druids.
Mark of Nature	Common	Druid	3	Choose One - Give a minion +4 Attack; or +4 Health and Taunt. Druids call it the "Mark of Nature." Everyone else calls it "needing a bath."
Overgrowth	Common	Druid	4	Gain two empty Mana Crystals. Zangarmarsh: it's a fungal out there!
Soul of the Forest	Common	Druid	4	Give your minions "Deathrattle: Summon a 2/2 Treant." "Reforestation" is suddenly a terrifying word.
Gift of the Wild	Common	Druid	8	Give your minions +2/+2 and Taunt. The gift that keeps on living.
Partner Assignment	Rare	Druid	1	Add a random 2-Cost and 3-Cost Beast to your hand. In every group assignment, someone does all the legwork.
Savagery	Rare	Druid	1	Deal damage equal to your hero's Attack to a minion. It is true that some druids are savage, but others still enjoy a quiet moment and a spot of tea.
Treenforcements	Rare	Druid	1	Choose One - Give a minion +2 Health and Taunt; or Summon a 2/2 Treant. Treemendous value!
Breath of Dreams	Rare	Druid	2	Draw a card. If you're holding a Dragon, gain an empty Mana Crystal. Ysera has the worst morning breath.
Dreamway Guardians	Rare	Druid	2	Summon two 1/2 Dryads with Lifesteal. They're a nightmare to deal with.
Ironbark	Rare	Druid	2	Give a minion +1/+3 and Taunt. Costs (0) if you have at least 7 Mana Crystals. "The important thing, son, is to protect your spores! I have spoken!"
Fungal Fortunes	Rare	Druid	3	Draw 3 cards. Discard any minions drawn. Far superior to a beanstalk boondoggle.
Bite	Rare	Druid	4	Give your hero +4 Attack this turn. Gain 4 Armor. Chew your food!
Germination	Rare	Druid	4	Summon a copy of a friendly minion. Give the copy Taunt. I regret asking how sporelings are made.
Aeroponics	Rare	Druid	5	Draw 2 cards. Costs (2) less for each Treant you control. Good seeds can go far.
Starfall	Rare	Druid	5	Choose One - Deal 5 damage to a minion; or 2 damage to all enemy minions. Is the sky falling? Yes. Yes it is.
Hidden Oasis	Rare	Druid	6	Choose One - Summon a 6/6 Ancient with Taunt; or Restore 12 Health. Amazing that it's been hidden, given the twenty-foot treant splashing around in it.
Nourish	Rare	Druid	6	Choose One - Gain 2 Mana Crystals; or Draw 3 cards. Druids take nourishment from many things: the power of nature, the songbird's chirp, a chocolate cake.
Overflow	Rare	Druid	7	Restore 5 Health to all characters. Draw 5 cards. It's a high five followed by a low tide.
The Forest's Aid	Rare	Druid	8	Twinspell Summon five 2/2 Treants. Delicious Forest's Aid! Made from real forests.
Embiggen	Epic	Druid	0	Give all minions in your deck +2/+2. They cost (1) more (up to 10). Did you set it to "wumbo?"
Secure the Deck	Epic	Druid	1	Sidequest: Attack twice with your hero. Reward: Add 3 'Claw' spells to your hand. "Tied it down, boss. I don't really know why you asked me to do that."
Crystalsong Portal	Epic	Druid	2	Discover a Druid minion. If you hand has no minions, keep all 3. Experience the draw of the wild!
Force of Nature	Epic	Druid	5	Summon three 2/2 Treants. "I think I'll just nap under these trees. Wait... AAAAAHHH!" - Blinkfizz, the Unfortunate Gnome
Glowfly Swarm	Epic	Druid	5	Summon a 2/2 Glowfly for each spell in your hand. Glowflies are distant relations to spelling bees.
Runic Carvings	Epic		6	Choose One - Summon four 2/2 Treant Totems; or Overload: (2) to summon them with Rush.
Guardian Animals	Epic		8	Summon two Beasts that cost (5) or less from your deck. Give them Rush. The guidelines specifically state: "Students may also bring an ironbeak owl OR an alleycat OR a toad." They never said how big.
Survival of the Fittest	Epic	Druid	10	Give +4/+4 to all minions in your hand, deck, and battlefield. Sometimes the fittest is the one smart enough to not start a fight with seven 6/6 Treants.
Untapped Potential	Legendary	Druid	1	Quest: End 4 turns with any unspent Mana. Reward: Ossirian Tear. The official term is "strategic laziness."

Leveling rewards[edit | edit source]

As a hero reaches various levels, they are awarded new cards, with each class having its own rewards. All cards awarded by gaining levels are uncraftable, and cannot be crafted or disenchanted.

Levels up to 10 award new Basic class-specific cards (one card every two levels), while levels after this award only golden versions of existing cards.

Starting cards[edit | edit source]

The Druid starts with the following class cards:

Levels 2-10[edit | edit source]

Up to level 10, reaching each even-numbered level will award the player two copies of a new Basic class card. These cards are not obtainable through any other means.

Level 2

Level 4

Level 6

Level 8

Level 10

Levels 11-60[edit | edit source]

Above level 10, reaching certain levels will award golden versions of existing Basic cards. As they are uncraftable, it is not possible to disenchant these cards, making the reward purely cosmetic. Reaching each required level will award one golden card. Levels after 10 award golden Basic class cards, whereas levels after 50 award golden Basic neutral minion cards.
