Runic Pyramid

Runic Pyramid is a boss relic that prevents your hand from being discarded at the end of each turn. Normally, any unplayed cards are sent to the discard pile when you end your turn, but with Runic Pyramid, those cards remain in your hand into the next turn. It is offered as a boss relic reward after defeating an Act boss.

Runic Pyramid is one of the most powerful boss relics for enabling complex card combos and hand-building strategies. By retaining your hand, you can accumulate powerful combinations over multiple turns and play them when you have enough Energy. This synergizes strongly with cards that gain value from being held (like Watcher's retain-based cards), high-cost combo setups, and builds that draw into a critical mass of key cards before executing. It also allows you to hold removal or defensive cards in reserve without wasting them. The main tension is with draw — if your hand fills up and your deck has few draw effects, you may stop drawing new cards at all since your hand stays full. It pairs best with decks that have some degree of hand management or selectivity in what they play, and it is nearly universally powerful once a deck has reached a certain level of quality.
