Void Form

RegentPowerRare
Ethereal.
End your turn.
The first 2 cards you play each turn are free to play.
  • It puts a Void Form power worth 2 on you and ends your turn at once, so play it last.
  • From the next turn on, the first 2 cards you play each turn have both their Energy cost and their Star cost set to 0.
  • Only cards you play by hand count, one the game plays for you, like Bombardment firing from the Exhaust Pile, uses no slot.
  • A second copy stacks the counter to 4.
  • Upgrade: drops Ethereal, so you can hold it for a quiet turn.

When to take Void Form

Take it when your deck already holds several cards costing 2 or more or with heavy Star costs, saved for elite and boss fights since the idle turn is the real price.

Changes by version

  1. Effects that make the next card free (Unrelenting, Void Form, etc.) now correctly take precedence over effects that increase all card costs (Entangled, Spiked Gauntlets, Borrowed Time, etc.)
    Fixed Vakuu's Whispering Earring relic not correctly playing Stardust card, auto-playing cards into the next turn after Void Form, and not letting Unceasing Top relic trigger when it plays your last card
  2. Fixed an issue where, if the player has Vakuu's Whispering Earring relic and it auto-plays Void Form card, it could sometimes continue auto-playing cards on the player's next turn
  3. Effects that make the next card free to play (Unrelenting card, Void Form card, etc.) now properly take precedence over effects that increase the cost of all cards (Entangled affliction, Spiked Gauntlets relic, Borrowed Time card, etc.)
