Diana
View on Wiki
Excellent (9/10)
Low Investment
Rare Relics OK
Diana is widely regarded as one of the most powerful and efficient champions in the game, capable of consistent first-turn victories. While her linear spell-chaining playstyle can feel repetitive, her sheer speed and low investment floor make her a top-tier choice for most encounters. She can struggle against the inflated health pools of Nightmare adventures, but remains highly effective.
The Turn One Nuclear Missile
Floods the deck with 1-cost copies of Pale Cascade, enabling continuous card draw and stat scaling.
Provides Fated and Augment to rapidly scale stats, granting Overwhelm once the Empowered 10 threshold is reached.
Generates a massive burst of spell mana on Turn 1 to fuel the Pale Cascade chain.
Strategy
This build is designed to end the game immediately upon Diana's summon. Hidden Tome provides the necessary spell mana on Turn 1.
By playing a cheap card to trigger Nightfall, summoning Diana, and chaining the discounted Pale Cascades generated by Echoing Spirit, Diana rapidly scales her stats. Chosen by the Stars accelerates this growth through Fated and Augment, quickly pushing her past 10 power to gain Overwhelm and Challenger for a lethal first-turn attack.
3-Star No Epics (Monthly Challenges)
Grants Challenger, Tough, and Overwhelm to ensure Diana can dictate combat and push damage.
Provides a substantial raw stat boost to increase her attack and health.- Stacks with the first Warhammer for massive early-game stats.
Strategy
This hyper-aggressive, high-stat focused strategy is designed for explosive, rapid assaults, particularly in Monthly Challenges. Full Build grants crucial keywords like Challenger, Tough, and Overwhelm, while double Caulfield's Warhammers provide a massive raw stat boost.
This allows Diana to quickly challenge key threats and push significant Overwhelm damage. It is especially potent in challenges with mutators like 'Forced Workout' or 'Combat Awareness', where her high stats and innate Quick Attack can dismantle the enemy board and Nexus rapidly.
Scout Speedrunner
Grants Scout, allowing Diana to attack twice per turn, synergizing perfectly with her innate Double Attack.
Causes Diana to strike an enemy upon summon. With Double Attack, this triggers twice, clearing blockers and dealing massive damage.
Grants the entire board Overwhelm, ensuring all excess damage from her multiple strikes pushes through to the enemy Nexus.
Strategy
This setup leverages the Scout keyword to maximize Diana's innate Double Attack, allowing her to strike up to four times in a single round. Stalker's Blade provides immediate board control upon summon, striking twice due to Double Attack.
Troll King's Crown ensures that small blockers do not absorb this massive damage output. Players disagree about Galeforce on Diana. Some consider it the ultimate speedrunning tool for aggressive clears, while others find the round-end recall effect and her resulting vulnerability to Frostbite or Stuns too risky for consistent play.
Budget Cascade
Generates a Fleeting Pale Cascade every round to guarantee card draw and Nightfall triggers.
Refills spell mana at the start of each round, ensuring funds are available for spells on subsequent turns.- Grants the entire board Overwhelm, ensuring Diana's scaled attacks hit the Nexus.
Strategy
For newer accounts lacking Epic relics, this build establishes a reliable engine. The Grand General's Counterplan ensures a steady supply of Pale Cascades.
Because Archangel's Staff provides spell mana at the start of the round after Diana is played, it ensures consistent funding for these spells on subsequent turns. Troll King's Crown is essential here, as Diana's high stats and Double Attack are easily mitigated by small blockers without Overwhelm.
Other Relic Options
Generates a spell every round, providing a guaranteed, cheap Nightfall activator for the mid-game when hand resources run low.
An excellent alternative to Troll King's Crown, providing Overwhelm and a stat boost to subtype allies.
Rallies upon leveling up, providing an extra attack token to close out games on the exact turn she flips.
Enables a control-oriented playstyle by granting Gloom to enemies via Nightfall units in hand.
Constellation
Diana is exceptionally powerful at her baseline 3-star level, often clearing high-difficulty content without the need for extensive Constellation upgrades. Her core loop of chaining spells and attacking multiple times makes her one of the premier aggressive champions, capable of bypassing complex encounter mechanics through sheer speed.
Outcast's Edge
Allies have "Nightfall: Grant me +2|+0."
Twilight Offering
+1 Starting Mana. When you play your first card each round, refill 1 mana.
Outcast's Edge II
Allies have "Nightfall: Grant me +2|+0 and Quick Attack. If I already have Quick Attack, grant me Double Attack instead."
Gameplay Tips
- Triggering Nightfall Effectively
Always play a low-cost card before summoning Diana or using key Nightfall units to ensure their bonus effects activate. Managing your hand to always have a cheap activator is crucial for maintaining momentum.
- Chaining Pale Cascade
Utilize Diana's champion spell to continuously buff her stats and draw through the deck. This spell-chaining loop is the primary win condition for most encounters, allowing her to out-scale opponents rapidly.
- Navigating Crowd Control
Be cautious of enemy regions with heavy Frostbite or Stun effects. Committing all your buffs to Diana can result in a stalled turn if she is incapacitated before striking, leaving your Nexus vulnerable.
- Maximizing Double Attack
Position Diana to strike the enemy Nexus directly or attack through small blockers once she has Overwhelm. Double Attack applies full damage twice if the blocker is destroyed on the first strike, making Overwhelm mandatory for closing out games.
- Exploiting Strike Mutators
Diana excels in monthly and weekly challenges featuring strike or attack-doubling mutators. Her innate Double Attack, especially when combined with Scout, allows her to multiply these effects for immediate victories.
