Field guide

Win the Eightfold Trial.

01

Protect your Core

Both players start at 30 health. Reduce the opposing Core to zero to win. Choose a 20-card deck with at most two copies of each artwork.

02

Spend your energy

You start with 1 energy and four cards. Each turn adds one maximum energy, refills it, and draws a card. Maximum energy is 10. Play units into one of five free positions.

03

Pick your battles

Select a ready allied unit, then an enemy unit or Core. Units exchange damage simultaneously and normally attack once per turn. New units wait one turn, unless they have Haste.

04

Awaken your element

Your Core power costs 2 energy and can be used once per turn. Spells resolve immediately. Cards with Arrival activate their ability when summoned.

Guard Must be attacked before other enemies or the Core.

Shield Prevents the next instance of damage.

Freeze A unit misses its next turn of attacks.

Lifesteal Damage dealt restores your Core health.

Hand limit Eight cards. Extra drawn cards are discarded.
