Systems and context

14Effects and combat subsystemsOverview and example ↗These mechanics are found in card games in general; in deck builder they create tasks for the build.10

Variants and applications

  • Damage / healing. Rule: Cards change the target's health immediately; Accessible purposes, price and reusability are important.

  • Alternate win condition. Rule: A separate combination or achievement allows you to complete the game differently than through the base goal.
  • Deck as health. Rule: Losing cards reduces your survival margin; exhausting the deck or failing to make a mandatory discard results in defeat.
  • Boss / stage gate. Rule: To continue, you must pass an opponent or a test that tests the specific capabilities of the assembled deck.

Differences That Affect Design

Discarding usually keeps the card in circulation. Permanent removal changes the composition of the deck for the rest of the game or run. Exhaust, in typical Slay the Spire fashion, removes a card from the current battle; in other games the term may have a different meaning. The deferred card is returned under a separate condition.

Strategy and mechanics. Thin or thick deck, engine, combo, rush, control, and "infinite" combination describe ways to use the rules. The mechanics themselves are the specific restrictions, operations, and bonuses that make such a strategy possible.

For specification. For each effect, it is worth specifying the source and target zones, the choosing player, the number of targets, the price, the moment of application, the period of change, randomness and resolution order. This combination of parameters describes the mechanics more accurately than a single keyword.

How to use the catalog

Separate player action, signal recognition, game rule, and feedback. The related variants here preserve the context of application and are not necessarily independent physical primitives.

When prototyping, test one rule and failure conditions first. The presence of an API, sensor, or source does not prove that all scenarios work. For devices, test feature availability, calibration, and alternate input on the actual target hardware.

Sources and examples

Sources support particular techniques or methodology, not every family variant. Design examples and mechanic combinations are illustrative.
