Monster Train 2 Pyre Hearts
You pick a Pyre Heart before each run. It sets your Pyre's starting Attack and Pyre Health, adds an effect, and gains more of both at Ring 3 and Ring 6. Most unlock from a lifetime counter that carries over between runs; the three Titan hearts need a Titan win. Unlocking six Pyre Hearts is also the first step toward the returning clans (see unlocking clans).
