Black Seal

Adds a rare single use seal that adds negative to a random joker.

A port of the original Black Seal mod to newer versions of Steamodded.

How It Works

When a card with black seal is used, it will apply negative edition to a random eligible joker.

Key Features

• Retriggers apply: Each retrigger of the seal will try to apply the effect to an eligible joker
• A single seal can apply many negative editions before being removed if done by a retrigger
• This behavior can be disabled
• Only one in deck (sort of): All other black seals in the deck will be removed when triggered
• Does not remove black seals in hand. Can be comboed with effects such as DNA. Can be disabled.
• Ectoplasm Override: Can override the 'Ectoplasm' spectral card to add a black seal instead of its normal effect
• Hand Reduction Toggle: When Ectoplasm override is active, you can also disable the hand reduction effect
• Rare Spawn: Can be found anywhere a random seal may appear, most commonly in booster packs (around 2% if no other seals)
• Configurable Spawn Rate: The spawn chance relative to all other seals can be configured (defaults to 10%)
• The spawn chance is absolute. For the remaining pool, the weights are normalized to remain proportional

Installation

1. Requirements: Steamodded and Lovely (mod managers install both automatically)
2. Recommended: Install from Thunderstore using the Thunderstore Mod Manager or r2modman
3. Manual: Download the latest release and extract its contents into a new folder inside your Balatro Mods directory (e.g. Mods/Black_Seal on Windows: %appdata%\Balatro\Mods) — do not extract directly into the Mods root
4. Configuration: Adjust spawn rates and Ectoplasm behavior through the mod settings

Configuration Options

• Spawn Rate: Adjust how frequently black seals appear relative to other seals
• Ectoplasm Override: Enable/disable replacing Ectoplasm's effect with black seal application
• Hand Reduction: When using Ectoplasm override, toggle whether the hand size reduction still occurs
