Excellent (8/10)
High Investment Required
Players disagree about Vex's baseline effectiveness. Some consider her early star levels underwhelming, while others appreciate her unique control tools. However, there is a strong consensus that she requires significant investment to reach her full potential. Unlocking her 4-star power and the 'Star of Discovery' constellation node transforms her into a highly effective and satisfying control champion.
Spell-Slinger Control
  • Loaded Dice icon
    Crucial for rerolling shops to find powerful damage spells, which synergize heavily with her constellation upgrades.
  • Big Guns icon
    Provides immediate spell damage amplification, allowing for early board clears and consistent Nexus damage.
  • Frozen Tomb icon
    Ensures Vex is on the board without spending mana, acting as a mana deposit and enabling early control.

Strategy

This build maximizes Vex's spell-slinging potential. The strategy revolves around drafting high-quality spells from shops and using them to control the board while Vex safely scales her damage.
Big Guns is preferred over Luden's Tempest because it provides immediate spell damage amplification from turn one without requiring Vex to be on the board. This allows early spells like Withering Wail to clear small, aggressive units immediately.
Frozen Tomb ensures Vex safely enters the board while preserving your mana for reactive spellcasting, allowing you to punish the AI when it overextends.
Resilient Control (No Epics)
Zoe Specialized
  • Voidborne Carapace icon
    Synergizes with Vex's playstyle, granting her additional keywords as units die.
  • Guardian Angel icon
    Provides a critical safety net, allowing Vex to play aggressively and survive otherwise lethal encounters.
  • Wicked Harvest icon
    Provides an immediate board clear, helping control the board and scaling her keywords.

Strategy

This build is specifically designed for the 10-star Zoe adventure, emphasizing board control and resilience without relying on Epic relics.
Voidborne Carapace allows Vex to scale her keywords as the board is cleared, while Guardian Angel ensures she can survive the massive stat scaling of Zoe's units. Focus on drafting removal spells and use Vex's Gloom to systematically weaken high-threat targets.
Infinite Gloom Engine
  • Chemtech Duplicator icon
    Provides overwhelming value in the late game by doubling her spells and Gloom applications.
  • Wicked Harvest icon
    Provides an excellent board clear upon Vex's summon, crucial for dealing with constant unit generation.
  • The Grand General's Counterplan icon
    Ensures Vex can be repeatedly played, re-triggering her summon effects to apply more Gloom.

Strategy

Designed for disruptive encounters, this build creates a cycle of control and damage. The Grand General's Counterplan ensures a continuous supply of Vex copies to replay her if she is removed or transformed.
Wicked Harvest provides an immediate board clear upon summon, which is then amplified by Chemtech Duplicator in the late game to double her Gloom application and completely lock down the opponent's board.
Gloom Chain Reaction
  • Fear-Cleaving Axe icon
    Scales her stats and synergizes perfectly with her level-up effect, amplifying Gloom application.
  • Utmost Despair icon
    Applies Gloom to the entire enemy board upon play, setting up immediate board control.
  • Black Shield icon
    Provides essential protection against removal-heavy encounters, forcing the AI to waste resources.

Strategy

Focused on maximizing Gloom application and scaling Vex's stats. Fear-Cleaving Axe synergizes perfectly with her level-up effect, amplifying Gloom application across the board.
Utmost Despair applies immediate Gloom upon play, setting up early control. Black Shield provides essential protection against removal-heavy encounters, forcing the AI to waste resources attempting to target her.
Other Relic Options
  • Searing Brilliance icon
    A strong option for spell-heavy playstyles, complementing her win condition of playing few units.
  • Riptide Battery icon
    Synergizes incredibly well with Gloom, providing multiple triggers that accelerate her level-up and clear boards.
  • The Curator's Gatebreaker icon
    Often paired with Riptide Battery for instant Gloom triggers and Nexus damage upon summoning.
  • Death's Foil icon
    Allows Vex to attack safely and apply Gloom without risking her survival against large blockers.
  • Echoing Spirit icon
    Excellent for generating additional copies of Vex and her champion spell, though it can occasionally clog the hand in longer encounters.
Constellation
Vex's power curve is highly exponential. At 3 stars, she struggles with high-stat encounters. However, her 'Star of Discovery' node (which grants +4 damage to drafted spells) is arguably the most important upgrade in her tree, turning her into a premium removal engine.

    Enables massive chain reactions and board wipes. Spreading Gloom as an AoE when enemies die outside of combat makes her incredibly satisfying and powerful, completely locking down enemy boards.
Gameplay Tips
  • Prioritize Spell Drafting
Vex's optimal playstyle revolves around casting spells rather than playing units. Aggressively cut units from your deck at healer nodes and use your rerolls at shops to find cheap, multi-target damage spells.
  • Bypass Enemy Defenses
Gloom is a status effect, not damage. This means it completely ignores defensive keywords like Tough and Barrier, and it will not trigger enemy powers that activate upon taking damage.
  • Master Mana Management
Because Vex relies heavily on spells, it is often correct to pass your turn and bank spell mana. Bait the AI into overextending their board, then punish them with a devastating area-of-effect spell.
  • Avoid Anti-Synergies
Be cautious with powers and cards that do not interact well with Gloom. The 'Enfeebling Strike' power does not trigger from Gloom application. Additionally, the spell 'Double Up' will deal zero damage to the enemy Nexus if the initial target is killed by Gloom. Finally, Vex's star powers convert damage to Gloom, which prevents champions like Veigar from leveling up and nullifies Jhin's damage-based star powers.
