The Rules of TerraForge

TerraForge is a game that is easy enough to learn, but requires a great deal of cunning and analysis to master.

Each game of TerraForge can effectively be broken down into five phases: primary phase, attack phase, defense phase, combat phase, and secondary phase. Each of these phases allows for certain actions to be performed, while restricting others. Understanding the freedoms and restrictions of each phase is crucial to the planning of an efficient strategy. Although certain actions can be played during multiple phases, it is important to assess the game state and determine which phase will yield the best results.

Sometimes the phase in which you play an action may be completely irrelevant in terms of the way it influences the present game state; however, it is still important to consider when actions are played, as in this case it is generally better to play the action at the last possible phase, thereby minimizing the amount of information you are giving your opponent.

If you're keen on understanding the specifics of each of the phases, then you should continue reading further below. If you find reading boring and just want to learn by example, then that's okay as well. There are plenty of tutorials available in game that will guide you through the basics of phases.

Primary Phase

The primary phase is the first playable phase during a player's turn. At the start of their primary phase, a player gains a single Terra charge and draws a card. After their tenth turn, players will not receive any additional Terra charges. The total number of Terra charges is refreshed at the beginning of each player's primary phase. Terra charges are the primary resource in TerraForge and are used to play the majority of creatures and spells in the game, as well as upgrade fortifications and activate abilities of weapons.

During their primary phase, a player may select up to one Eternal to invest in. Eternals serve as threshold requirements for playing the majority of cards. Players will not be able to make more than ten Eternal selections throughout the game, so it is important to build your deck accordingly. Players may play any cards during their primary phases, provided the Eternal threshold is met and they have a sufficient number of Terra charges available.

Attack Phase

The attack phase is, as the name implies, the phase in which players may declare any and all attacks they wish to make during their turn. Typically only creatures played in the front row may attack and they may only attack the enemy Avatar or enemy creatures in the front row and same column as themselves. Both players may only play surge speed spells and abilities during the attack phase. Spells and abilities may be played before and after attack declarations are made, but not while declarations are being made.

Defense Phase

During the defense phase, the defensive player has the opportunity to declare any and all defending creatures that they wish to. If no attacks were made during the attack phase, then the defense phase is skipped. Defending creatures can defend either the Avatar or creatures that are being attacked. Defending creature can typically only defend against attackers in the same column as them. Both players may only play surge speed spells and abilities during the defense phase. Spells and abilities may be played before and after defense declarations are made, but not while declarations are being made.

Combat Phase

The combat phase defines when all of the damage dealt by attackers and defenders is effectively calculated. During the combat phase, players may not play any spells or abilities unless a stack is created as a result of triggers occurring during the combat phase.

Secondary Phase

The secondary phase is the last phase in a player's turn. The secondary phase follows the exact same rules as the primary phase. If an Eternal was selected during a player's primary phase, one cannot be selected during their secondary phase. Upon passing the secondary phase, the opposing player's turn begins and they enter their primary phase.
