Duelyst patch 1.68 rolled out today, bringing with it a lot of new stuff. Of note in the patch are the new Prismatic Cards — which are ‘foil’ versions of existing cards, and a variety of loot crates ranging from common to epic. Prismatic form is a 100% cosmetic change that doesn’t impact gameplay. Every card now has this form as well as its normal one. Cards found in a spirit orb can be upgraded to Prismatic and players can craft them on their own using Spirit.
Loot crates are pretty much as they sound; crates filled with cosmetic goodies, Prismatic Cards and game content. They provide players with an additional way to obtain high-rarity cosmetics.
In addition to these two things, the Duelyst patch notes also highlight new cosmetics and emotes available in the armory, new card backs, an update on the game’s progress in coming to Steam, and a card lore update. All of these can be read about in the patch notes on the site.
