Prismwar is an original six-color card battler from DHSeaDev: White, Blue, Black, Red, Green, and the new sixth color, Purple, the Undertow, which takes your opponent’s units for good. Play it against a computer rival in the browser, build decks, earn packs from quests and achievements, and unlock the ten Ascendants with codes posted here. The full write-up is on the Prismwar project page.

Your Ledger Card

Inside the game, open the Ledger tab. It prints a card with your collection count, packs opened, win-loss record, achievements, Ascendants and deck list, followed by a Sig line that fingerprints those numbers. A card whose numbers were edited will not match its Sig, and a save modified outside the game says so on the card itself.

Three ways to share it. Post to the Ledger Wall sends the card, as a stylized card, to the shared Ledger Wall at the DHSeaDev Arcade, where every player’s card sits together. Download picture saves it as a PNG you can post anywhere. Copy text gives you the plain block below. The wall is a playful shared list, not an audited leaderboard. Posted cards are public: the Prismwar privacy policy explains what a card contains and where it is stored.

Codes and the Ascendants

Ten legendary Ascendants sit above the 240-card Refraction set. They never appear in packs. They unlock only with codes issued here by DHSeaDev, each digitally signed so the game can tell a real code from a forged one. Codes will be posted on this page and in devlogs; enter them in the game’s Redeem tab. Deck codes from the Decks tab can be shared the same way so others can try your build.

Where to play
